• Every wail popup must show directly on top of all opened windows.
• at least, on mac os, move to the desktop where the wails popup is, if possible

Couldn't reproduce on MacOS and Windows. The windows opened by the wallet are shown on top

If we want, we could force windows to be always on top using the AlwaysOnTop option

@longgamma-massa nothing to QA for now, still in TODO, needs research and UX/UI discussion about what is needed and what is possible to achieve, on the 3 OS
