Steps to reproduce the behavior:

Expected behavior
Text input is not limited to any amount of characters or at least is limited to max-input-chars from mods settings.

Additional context
This doesn't seem to be related to max-input-chars settings, as value there was generous (in my setup max-input-chars: 392000)
