Fix the infinite resizing freeze

This appears related to libpango somehow, as in Debian
Bullseye, libpango splits URLs with dashes at the end,
but in Debian Bookworm, the URLs are not split with dashes
at the end, and the bug does not appear to be triggered
in Bookworm.

This patch makes the assumption that the gtkimhtml widgets
stored in a PidginConversation normally resize in an
alternating manner. However, when the bug is triggered,
only the "entry" gtkimhtml member of PidginConversation
resizes, so we allow "entry" to resize only up to 3 times
in a row.

Testing Done:
Compiled and tested on several desktop environments on a few
GNU/Linux distros by pasting the link mentioned
here https://issues.imfreedom.org/issue/PIDGIN-17413 moving
the cursor at the beginning of the buffer, and holding
the spacebar pressed.

Bugs closed: PIDGIN-16753, PIDGIN-16999, PIDGIN-17287, PIDGIN-17413, PIDGIN-17430, PIDGIN-17568, PIDGIN-17602

The Penguin
by Rob Flynn <rob@marko.net>
and
Jeramey Crawford <jacrawf@marko.net>
Once upon a term'nal dreary, while I hack'ed, weak and weary,
Over many a quaint and curious volume of forgotten code--
While I nodded, nearly napping, suddenly there came a beeping,
As of some one gently feeping, feeping using damn talk mode.
"'Tis some hacker," I muttered, "beeping using damn talk mode--
Only this. I hate talk mode."
Ah, distinctly I remember it was in the bleak semester,
And college life wrought its terror as the school year became a bore.
Eagerly I wished for privledges;--higher access I sought to borrow
For my term'nal, unceasing sorrow--sorrow for a file called core--
For the rare and radiant files of .c the coders call the core--
Access Denied. Chown me more.
"Open Source," did all mutter, when, with very little flirt and flutter,
In there stepped a stately Penguin of the saintly days of yore.
Quite a bit obese was he; having eaten lots of fish had he,
But, by deign of Finnish programmer, he sat in the middle of my floor--
Looking upon my dusty term'nal in the middle of my floor--
Came, and sat, and nothing more.
Then the tubby bird beguiling my sad code into shining,
By the free and open decorum of the message that it bore,
"Though thy term'nal be dusty and slow," he said, "Linux be not craven!"
And thus I installed a new OS far from the proprietary shore--
The kernel code open but documentation lacking on this shore.
Quoth the Penguin, "pipe grep more!"
Much I marvelled this rotund fowl to hear discourse so plainly,
Though its answer little meaning--little relevancy bore;
For we cannot help believing that no living human being
Ever yet was blessed with seeing bird in the middle of his floor--
Bird or beast sitting in the middle of his cluttered floor,
With such instructions as "pipe grep more."
But the Penguin, sitting lonely in that cluttered floor, spoke only
Those words, as if its soul in that instruction he did outpour.
Nothing more did he need utter; understood did I among that clutter--
Understood his command as I could scarcely do a few moments before--
I typed as furious as was willed me, understanding just a minute before.
Again the bird said "pipe grep more!"
"Amazing!" said I, "Penguin we will conquor the world if you will!
By the Network that interconnects us--by that Finn we both adore--
We'll take this very world by storm!" For now grasped I what he'd meant,
The thing I do while searching /usr/doc/* for that wond'rous lore--
Those compendiums of plaintext documentation and descriptive lore.
Quoth the Penguin, "pipe grep more!"
And the Penguin, never waddling, still is sitting, still is sitting
In the middle of my room and still very cluttered floor;
And his eyes have all the seeming of the free beer I am drinking
And the term'nal-light o'er him glowing throws his shadows on the floor;
And this OS from out the shadows that is pow'ring my term'nal on the floor
Shall be dominating--"Pipe grep more!"
