Some operations are ignored for Undo

harrrrrry

When composing a message, it's generally expected that Undo should always undo the previous operation.

But there are some occasions where this is not happening.

Control-B (bold) inserts the asterisks needed to surround bold text. Afterwards, control-Z (undo) ought to be able to delete them, but currently does nothing. A second control-B does remove them, But control-Z should remove them too.
The Insert Spoiler icon spoiler inserts [SPOILER] [/SPOILER] but Control-Z does not remove it. Actually, it removes whatever was typed immediately before the spoiler leaving the spoiler tags in place, which is even more confusing.

I'm sure there are other occasions too. But those are the occasions where I see the problem most often.

Another one:

put some text on the clipboard
press control-V -- the clipboard text is inserted as expected
now press control-Z (undo)

Present behaviour: nothing happens

Expected behaviour: the text from the clipboard should be removed again

harrrrrry so this is what I did...
Typed in "help" selected text pressed ctrl c, deleted then ctrl v pasted then ctrl z and did what supposed to do "undo" ctrl z is not to delete from clipboard it is to undo last operation. So if last operation was copying to clipboard then ctrl z would delete

Sorry if a bit long winded, that's just me.

And if anyone wants to do this on an android phone then I would recommend "Hacker's Keyboard" from play store.

I don't expect undo to remove the text from the clipboard, only to undo the insertion of the text from the body of the post,

Curiously I do find that sometimes undo does exactly that. It's doing it corrrrectly at the moment. But it has failed many times in the past and it wasn't working when I rechecked it at the time I wrote the post.

It may perhaps depend on where the pasted text came from in the first place. I'll do some more tests.
