[FR] expand all nested tags if there are no notes in the intermediate tags

[afland]

Say you only have 1 note in your vault with #topic/dev/java

Expanding all of those individually is unnecessary because you only see a note once you get to the java nested tag anyway.

So when you click expand on any tag (parent or any level nested tag), all nested tags below that should be expanded until a note is encountered.

I thought this behaviour is as like as Java repo of GitHub, and implemented so on v0.14.1. Could you please check the behaviour?

Note: If three normal tags are nested, they will not be merged into one tag. (To find a note out, I think we will choose the tag in order of just remembered) If you want to merge them, please enable Merge redundant combinations on the setting dialog.
