[Web] Inserting spaces break the line randomly at some point

[NicolasDionB]

My issue is about [Web], when composing text, inserting multiple spaces eventually makes the text fall on the next line even when there is still space left on the right. For instance, using the example editor, if I insert spaces between words (about 114 for this very example), until this point:

Everything is fine until I insert another one, then the text falls on the next line, like so:

If I play with that I get some strange and inconsistent behavior, sometimes getting the carriage return sooner or sometimes it is fine. I cannot get the exact repro case but just playing with it does the trick.

While this may seem trivial, as it is not consistent, I can get the problem typing normal text, which is more concerning. I also tried it in the example on the numeric list items and when I get the line return, it actually creates a new list item! So it's really behaving as if I hit the return key, which I did not. If I then use backspace to remove the return, I can add more spaces and everything seems fine after that.

I'm running Flutter Quill 3.8.3 (master) with Flutter 2.8.1 on Chrome 97.0.4692.99, Windows 10.
