input_pill: Fix backspace with selected text.

Browse Source 
The logic added in b57ebe717e introduced
a different bug, namely that if you had selected text in the input,
Backspace would delete the input pill itself, not your selected text.

Fix this, without re-introducing the old bug, by checking explicitly
if there's a range selected before inspecting anchorOffset.

Also improve the comments.

Fixes #19544.
