Unable to Reopen Font in Text Filter

Open Other > Colour > Transparent.
Add Text Filter > Change Font from Verdana to Trebuchet MS.

Realising I’d not set the correct font size I clicked on the font button in the add text filter again to reopen the font settings but they will not open.

Regards

Just discovered the dialog had opened behind the main window.
Should it come to the top when the font button is clicked again (i.e. even if the dialog is already open)?
