Wiki edit cursor sprite and position desync with each other after useless text selection drag n drop

[GitPerseus]

When editing a wiki page, if you select text, then use the mouse to drag it around, then place it back on it's original location,
the writing cursor's sprite will desync with its actual position, which is kinda annoying.
Afterwards, dragging text then dropping it anywhere else resyncs the sprite with the writing cursor's position.

(I don't know if this is a bug with the wiki itself or some other program/resource that the wiki depends upon to support text edition,
but even in the latter case, i thought it would be at least worth mentioning here for informative purposes.)

This is very strange, I can't reproduce this at all. For the text editor, I am using the builtin browser text edit control, so any issues there are probably browser issues. What OS/browser are you using?

Oh right, i thought of mentioning the browser i use but forgot when actually writing this issue, sorry about that.
I'm using Firefox on Linux.
