[TYPO3-core] RFC #14920: Cache cannot be cleared in IE8

[Ernesto Baschny [cron IT]]

Hi,

please consider the attached patch, as it uses the replace() function,
which is much cleaner way of replacing an icon back and forth.

This doesn't work in IE8:

	Element('span', { 'class': 'spinner'});

This works and is also how it is documented at the prototype API.

	new Element('span').addClassName('spinner');

Adding the classname after creation is a fix needed to make it also work
on IE8.

Same issue applies to the "shortcutmenu", it is currently not possible
to add any backend module as a shortcut with IE8. I filed #15252, please
review that patch too (RFC in a couple of minutes), because it is the
same solution.

Cheers,
Ernesto
