numbers column behaviour on focus

[arthur-s]

Warning: I will close the issue without the minimal init.vim and the reproduction instructions.

Problems summary

On nvim, when I open defx, I don't see the numbes column, see image: https://ibb.co/qncCv7j

Then if I switch focus from terminal to another program on my desktop, e.g. I open web browser, then again switch back to terminal, I can see numbers appeared: https://ibb.co/d4fLDs0 on vim8 numbers doesn't appear at all.

Expected

numbers columns should always be displayed when defx open.
