[TYPO3-core] FYI: Fixed bug #15818: htmlArea RTE: Erratic behaviour of toolbar in some browsers

[Stanislas Rolland]

FYI: The attached SVN patch was committed.

Type:
Bugfix

Problem:
The behaviour of the RTE toolbar may be erratic in some strange ways in 
TYPO3 4.4+;

In IE7, when setup.override.navFrameResizable = 1 is set in 
UserTSConfig, the toolbar buttons are just not reacting. (See issues 
0015546 and 0015667).

In WebKit browsers, the focus is stolen on every second click in the 
toolbar, resulting in erratic behaviours of the RTE. (See issue 0015329).

Solution:
The attached patch works around the issue, presumably somehow caused by 
ExtJS, by replacing the clickevent on toolbar buttons by a mousedown event.
