Browser undo is on haywire

[avcs06]

Browser undo is working unexpectedly in all fields.

Possible solution:
Custom Undo behaviour, but it is too much unnecessary code for someone who doesn't need it. If user is using any wysiwyg editor they come with their own undo behaviour and this code becomes redundant.

Less possible solution
Figure out how to tap into browser undo history stack and manipulate. Need to figure out if it is even possible.
