Hover shows balloons but not floating preview

[egorbn]

Hi folks,

$ vim --version

I'm able to hover and see balloons, but when I set
let g:ale_hover_to_floating_preview = 1
the mouse hover popups disappear

At the same time, when I issue :ALEHover a floating preview window does appear!

So it looks like the mouse gets picked up for balloon hover, but not floating preview hover, even though the floating preview can be shown with the command.

Any ideas?

I'm currently binding ale_hover to a leader command, but it would be great if the mouse hover worked, too.

Thanks!
