Can't input lowercase "t"

[Velenir]

Don't know when the problem appeared, but currently on Ubuntu 18.04, Google Chrome Version 70.0.3514.0 (Official Build) dev (64-bit) I can't input a lowercase letter t. Nothing happens, as if the event is intercepted.

Shift+t produces T as expected. Symbols I have on that keyboard button in a different locale work as expected.

No problem on Chromium Version 68.0.3440.75
