Bug: The gallery title is only clickable after clicking on an image

When I add a new gallery, I can't add a title right away. The "Add a title" text is not selectable. However, if I add some images, click on one to view it in fullscreen, and then go back, I'm able to add the title. Could you please fix this issue? I'm using Firefox v129.0.1, and I believe this problem started about two months ago.
