layout update file buttons

[MAETempels]

Pages Symmetry and Reflect have "upload file" functionality.

The buttons to select a file are not conform the "buttons.css".

Applying this css set the border also around the text about the file.

Page sheet also has update-functionality, but without buttons.

As you experienced an input-type-file is more than a button. Styling the inner button requires a complex detour that hides the actual input tag and mimics the behavior with other visible tags. I don't think we should go don that lane.

I am not able to change the status of this issue to "won't fix".
