[TYPO3-rte] Changing link targets leads to multiple targets

[Markus Stauffiger (4eyes GmbH)]

Hi there

I'm working with TYPO3 4.4.2, having a problem when changing the target 
of a link.

Lets say I first select "_top", which will work fine. Next I change the 
target to "_blank". No RTE generate the following link:

<a target="_top _blank" href="http://test.domain.com/?id=30519">test</a>

Any idea where the multiple targets come from?

Best regards
Markus
