when you close one tab in kate text editor (CTRL+W) , you can realize which button has the focus, meaby with a blue color (kde applications) or with a dotted line on the button. You can use left/right arow or TAB.
Kate text editor
But in some applications (GTK+), is impossible to know so and left/right arrows or TAB doesn't work properly in these cases. For example in Firefox when you have more than one tab after close the app (ALT+F4).
Similar in vscode, when you close one tab (CTRL+W).
Is there a way to work around that behavior?
Is there a solution?, thanks in advance.

On vscode TAB key, Left/Right Arrows key, ALT+underline letter works well.
On Firefox only ALT key work but "close tabs" button never is colored, Arrows key doesn't work properly.
