Tab characters don't get properly converted to spaces

[Mex]

When pasting data into the editor, tab characters don't get converted properly to spaces.

Firefox seems to work well, and IE sort of works, here's the results:

Browser (Browser Version) - Spaces Per Tab Character

---

Firefox (9.0) - 4

IE (9.0.8112.16421) - 1

Opera (11.60) - 0

Chrome (16.0.912.63 m) - 0

Safari (5.1.2) - 0

I'm an Opera user, and am having to indent code manually after pasting it in, due to tabs being converted to 0 spaces.

@Mex Where do you paste this text from? Could you perhaps give us sample file with this tabbed text so that we could see the problem for our selves?

example of text to cut/copy

i copy the text from Notepad or Notepad++.

i've uploaded a file with a tab on the 2nd line, when you paste the entire file content's into the editor, the b character doesn't get indented.
