To recreate the bug:
- Go to a textarea
- type a character on the first line
a
- hit enter
- type another character on the second line
a
b
- add a space in front of the character
a
b
- place the caret to the beginning of the second line (before the space) and hit delete so that the second line is concatenated to the first line
a b
- press the right arrow to get to the end of the line
The caret will not advance past the second character but you will actually be past it and can delete it.
Always happens as far as I know. Doesn’t have to be on the first two lines, can be on any consecutive lines but it will go past the second character, it just needs an extra hit of the right arrow key.
It doesn’t happen in Firefox or Chrome.
