Rearranging hierarchical tags not working
Mandatory: Shotwell version the issue was seen with
Shotwell 0.30.1 Platform: Chrome OS/Crostini (Debian Buster)
The expected behaviour
From documentation: "Shotwell supports also hierarchical tags. You can rearrange your tags by drag and drop a tag onto another."
What was actually happening
Dragging a tag creates a small "panel" with the name of the tag and + sign top left. When the panel is released onto another tag or in between tags, instead of adding the tag the panel shoots across the screen to the right and no change is made to the tag hierarchy.
Steps to reproduce the issue
This has been tried with various tags at all levels of the existing hierarchy and the behaviour is always the same.
