GtkComboBoxText (with Entry) inside a 'toolbar' style GtkBox loses visual connection of Entry and Button
Steps to reproduce
- gtk4-builder-tool preview ./combobox.ui
Current behavior
In the attached combobox.ui the first two comboboxes have a visible border around the GtkButton and a junction between the GtkEntry and GtkButton, but the 3rd one has no border around the GtkButton part of the GtkEntry which makes it appear disconnected from the GtkEntry. Adwaita theme.
Expected outcome
That the GtkComboBox feels more as a single widget than a pair of unrelated elements.
Version information
