Bug ID: 463201
Summary: Unable to display tooltips and repeated display
requests when using a custom widget
Classification: Plasma
Product: Breeze
Version: 5.26.4
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: gtk theme

Target Milestone: ---
SUMMARY
***
A recent change in the Xfce4-panel code brought up a bug [1] that I think comes
from this theme. The other tested themes do not have this problem, I don't
think anything bad is done in the GtkWidget::query-tooltip signal handler [2],
and simply replacing `gtk_tooltip_set_custom()` with
`gtk_tooltip_set_text/icon()` allows the tooltip to be displayed again (however
`gtk_tooltip_set_custom()` is required here).
