Tags plugin: sometimes crashes on empty tags about mkdocs-material HOT 3 CLOSED

Released as part of 9.5.19

from mkdocs-material.

Hello! I noticed that many of my notes currently have empty tags in the metadata section. Are these empty tags considered valid for mkdocs?
I just encountered an exception in the source code related to this when I execute build/serve process to create a blog. And the exception which I've already addressed by making modifications and testing them thoroughly.
Everything seems to be working smoothly now (just made a simple test)🎉🎉! Or are there any spec considerations I might have overlooked?
I have just gone ahead and created a pull request for this issue: #7098.

Thanks for reporting and creating the PR! I've ran your reproduction, and can't observe the problem. However, looking at the code, your proposed changes definitely make sense to better safe guard against such errors, and I can't rule out that it might be related to some other version of some other package that is causing the problem.
