At random times, the Brave browser stops taking keyboard input, either from physical or virtual keyboard. The behavior happens randomly, and the only way I can find to fix it is to completely close all browser sessions and re-launch them. This is very annoying because all in-progress browsing sessions are lost and many are unrecoverable.
Reproducing the issue: Since this happens randomly, the only way to get it to reproduce is to wait patiently.
Result: the only way to enter text into anything in the browser (text fields, address bar, keyboard shortcuts, etc.) is to copy it from a text editor and paste using mouse-clicks.
