Problem

In some circumstances the browser sends on segment saving nested DEL tags to the server.

This leads to "Notice: No valid HTML in translate5 segment" errors on the server.

The segment could not be saved then.

Todo

1. Investigate how it could be possible to get nested DELs in the editor.
2. Investigate why the algorithm which cleans the HTML in the JS does not prevent such nesting

Results

1. Could not reprocude nested DELs.
2. The algorithm does clean nested DELs as in the example.

Solution (hopefully):

• handle TrackChanges also when leaving segment by doubleclicking another segment
• run the complete cleanUp-process also before saving, always
