fix: detect sections correctly

[luckman212]

Abstract

I noticed today that I was getting JS errors in the console when trying to use the Copy URI for current block command under certain conditions:

A section with no text in it e.g.

# Section I haven't written yet

{cursor here} <==

# Another section
...

Cursor at very end of file

File empty / contains no sections

Here's a PR I came up with that resolves these cases. I did some testing and seems fine, but please comment with any more changes needed.

Screenshots from this fork

empty section

end of file

empty file

Anyone who wants to test without setting up the nodeJS dev environment can grab the compiled main.js here and replace the one in .obsidian/plugins

main.js.zip

@Vinzent03 I squashed the multiple commits, and pushed an updated version. Can you please take a look when you have a moment? 🙏

N.B. still working after Electron 30 / Obsidian 1.6.5 update
