1. Enable Git Change Bar. 2. Enable line wrapping in Geany Preferences → Editor. 3. Open a file that is under Git control (can’t reproduce on files that had been opened before line wrapping was enabled). 4. Change a (short) line in that file. 5. Point the mouse on the margin indicating a changed hunk.

Result: the line is wrongly wrapped in the tooltip (and its ending cannot be seen because of #425):


Expected result: same as with line wrapping disabled:


Note: #425 is about the fact that the wrapped part of the line cannot be seen; this issue is about the fact that the line should not be wrapped in the first place.
