When hiding an overriding text-indent value and then hiding the overflow:hidden value, the element doubles in width. With every consecutive toggle of visible/hidden for the overflow value, the element increases in size by it's original width.
Can only reproduce the behaviour with these conditions:
Elements parent has width of auto
Elements parent is either 'inline-block' or 'floated block element'.
Element has a width of auto
