Text Format plug-in not working with checkbox lists

The “Capitalize only first word of sentence” command in the Text Format plug-in doesn’t work with checkbox lists.

I do a lot of voice dictation into Obsidian notes on my Mac, and because Obsidian’s not a native Mac app, the first word of list items is usually not capitalized.

So, I frequently select a stack of bulleted items and use the “Capitalize only first word of sentence” command. This works fine on bullet and numbered lists, but not Obsidian’s checkbox lists. Is there some workaround I could employ?

(I’ve also posted this on the plug-in’s GitHub page.)
