Tab bar steals focus; dangerous
I'm not sure when it started, but using the version of Gnome-Terminal in latest ubuntu (GT 3.34.2), I regularly find the tab bar stealing keyboard focus.
This is dangerous.
The problem is usually that I click on a tab, leave the mouse there, and start typing. The tab bar then steals the first character typed. Sometimes I click in the terminal window, and then move the mouse out of the way (to the tab bar). Sometimes it happens later, when the mouse drifts onto a tab (maybe I knock it slightly while typing).
There are many cases in which the unexpected loss of a character typed could lead to significant damage. For example,
losing the tilde. Or
sudo rm -rf /mnt/1/*
losing the 1.
I have preferred click to focus (as opposed to focus-follows-mouse) in X for nearly 30 years. Gnome-Terminal should not pervert this preference.
