Just encountered a behaviour in IE8 that could be considered a bug.
I've got a page which renders X (to make it abstract) in IE8 on one PC and
renders Y on another PC.
The page contains the X-UA-Compatible tag, so you would think that it's not
an IE8 problem, but something different.
After digging - the website was in the Compatibilty View list on one PC and
not on the other.
Adding the X-UA-Compatible tag to the page (and the whole site actually)
hides the button to turn on/off the Compatibility View next to the refresh
button. It has to be done through the menu, but no normal user does that I
guess, only developers.
So if you turned on Compatibility View before the meta tag was added, you
get different rendering compared to never having turned on Compatibility View.
I was to believe that the meta tag forced the Compatibility View, but
apparently it does something else here.
