Bugfix RT58605
It was not possible to delete a br, hr or img tag at the end of an inline element (like an a) by pressing the “delete” button. This has been fixed now.
Bugfix RT58603
When pasting content containing an acronym-tag, those tags were not handled correctly.
This has been fixed now. It is however important to note, that the acronym-tag is not part of the html5 specification anymore and should be avoided in favor of the abbr-tag.
