Pressing `Esc` in delete/change operation still deletes the character your cursor is over

[Lamby777]

If your cursor is on the first line...

aaaaaaaaaaaaaaa
aaaaaaaaaabaaaa

and you want to do dtb but then press Esc instead of b because you changed your mind, it still deletes whatever character you're on, making it

aaaaaaaaaaaaaa
aaaaaaaaaabaaaa

Easily reverted with an undo, but still pretty annoying.

I can reproduce this bug. I was wondering if this might be the default Vim behavior, but it turns out that it isn't.

Starting Vim without any plugins and pressing dt<Esc> while the cursor is on the first character of aaaaaaaaaabaaaa doesn't delete anything.
