Funny German Umlaut Behaviour

When I try to position the cursor between two letters, it doesn’t work, if it is placed directly after a German Umlaut.
For example if I have the word “hätte” and I want to place the cursor between “ä” and “t”, it jumps to the beginning of the new line instead. If I try it 2 or 3 times, sometimes it will work, but never for the first attempt.
I didn’t notice that before and it doesn’t happen with the german sz “ß”.
