Mapping <Tab> to za (open/close fold) effects <C-i> (go back in jumplist). Is this a bug?

[Maltimore]

I don't want to spam the issues section with something that is not a bug and just me misunderstanding how this mapping works, so I'm posting here first.

To reproduce:

• nvim --clean
• perform a jump somewhere, e.g. open a random text file
• :nnoremap <Tab> za
• C-o to go back in the jump list
• C-i to go forward in the jump list

Observe E490: No fold found
I don't understand how doing this mapping (which seems completely unrelated) can have that effect.

:h <Tab>

And, if you are using Konsole (which you mentioned in one of your issues), it doesn't support this.

Thanks a lot! I learned something new today (the help section you linked an the tmux issue linked there are very informative).
