[Bug 1926256] Re: Pasted text in the terminal is always highlighted and selected

[Cubic PPA]

This bug has been marked as invalid for gnome-terminal because it is a
feature of bash shell.

However, should we mark gnome-terminal as impacted?...

I see the benefit to the change in bash from a security perspective, so
perhaps gnome-terminal needs to adapt to this new feature.

Specifically, I think this behavior could be confusing to users:

For example, @Egmont Koblinger suggested changing the high-light color
in the terminal, so it does not match the "bracketed paste" color. This
can be done through the color profile for gnome-terminal. This is one
option, but it may have implications for accessibility (people who can
not distinguish different colors due to color-blindness).

There may also be other things that gnome-terminal cold do to adapt to
this change.

Therefore, may be we should leave gnome-terminal as impacted for now, so
a good solution can be devised?
