When I assign tags via the Information panel, they are displayed in the Information panel and I can search for them via tags:/.
When I try to assign them via right-click -> Properties -> Information -> Tags: Add Tags..., they are displayed under Properties -> Information -> Tags, but not on the Information panel. They are also gone when I right-click -> Properties -> Information again, and I cannot find them in tags:/.

Reproducible: Always

Steps to Reproduce:
1. Right-click a file, select "Properties", select the "Information" tab, click on "Add Tags..."
2. Add Tag(s), close "Properties" window by clicking "OK".
Actual Results:  
Information panel does not show Tag, right-click/Properties/Information does not show Tag, file is not listed under tags:/{Tag name}/.

Expected Results:  
Information panel should show Tag,  right-click/Properties/Information should list Tag, file should be listed under tags:/{Tag name}/.

Workaround: Assign tags via the Information panel.
