Actually, I just tested this with Sigil-1.9.2 and here is what I am seeing:

Insert ID - adds an attribute id="blah" to a single or opening tag. It works as expected. If the insertion point is anywhere after the tag name even just before the ending ">".

Insert File (Image or Media) - adds an img, video, or audio tag and it must be outside of opening or closing tags and it appears to work as expected.

That said

Insert Link - adds an anchor tag if needed and sets the href to the selected destination.
It must be added outside of opening and closing tags or in an existing anchor tag. This one has an issue with the cursor right before the start of an tag (ending </p>) and it needs the workaround.

You should be seeing the same thing. Please let me know if you are not just in case I am missing something in my testing.
