Sorry, but this fell through the cracks. Good news is that it will be in the first 19.0.1 hotfix due out shortly after 19.0.1 is final.
In the meantime, if you are comfortable with Slick-C, you can hack this in yourself:
In macros/se/ui/toolwindow.e, around line 1807, change:
focus_to_wid._set_focus();
to:
if ( _get_focus() != focus_to_wid ) {
focus_to_wid._set_focus();
} else {
focus_to_wid.call_event(focus_to_wid, ON_GOT_FOCUS, 'w');
}
Save and load the module (Macro>Load Module).
