Application grid fails to appear or disappear

[Zolt]

https://github.com/home-sweet-gnome/dash-to-panel/issues/1469

What you expected to happen:
gnome-shell application grid to behave normally

What actually happened:
Upon clicking the show applications button once and reopening overview, applications do not show up. When clicking the button twice to open/close the application view, the grid will briefly flash on second click, and after closing and reopening overview the grid will persist in the main overview behind open windows.

This bug seems to be triggered by dash-to-panel when configuring settings to use the default gnome-dash/applications button and disabling the button on the panel. It's also very similar to https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1922353

I've recreated this bug on ubuntu 21.04 with vanilla gnome as well as pop_os 21.04 and ubuntu 21.04 with default extensions disabled.

Error log:
value "nan" of type 'gfloat' is invalid or out of range for property 'translation-x' of type 'gfloat'
value "nan" of type 'gfloat' is invalid or out of range for property 'translation-y' of type 'gfloat'
value "-nan" of type 'gdouble' is invalid or out of range for property 'value' of type 'gdouble'

Steps to recreate:
1) Disable any built-in extensions that modify gnome-shell
2) Install and enable dash-to-panel, toggle 'show applications button' off and 'activities button' on and enable 'keep original gnome-shell dash'
3) Restart shell and click show applications button on the dash

Sounds like a bug in dash-to-panel only. There might be some hints as to what needs fixing in bug 1922353 or bug 1918874.
