[TYPO3-core] RFC #16049: Loading mask doesn't disappear on hitting Esc/cancel loading

[Steffen Gebert]

Hi!

This is a SVN patch request.

Type: Bugfix

Bugtracker reference:
http://bugs.typo3.org/view.php?id=16049

Branches:
trunk

Problem:
When the loading mask "locks" a frame and you hit Esc or cancel loading 
of the page, the mask *must* disappear (imagine you have unsafed changes 
there in this frame!)

Solution:
Unfortunately there seems to be no perfect solution, as there is no 
event fired on aborting (which is somehow good, as it keeps the control 
on the page's code on the user's side).

I decided to make the spinner icon clickable, so if a user cancels 
loading (imagine unsaved values in a TCEform and you click on a page in 
the tree by accident --> Esc), the mask can be removed and content made 
accessible again.


Kind regards
Steffen
