how to make Button respond to its image child?

[PasswordIsntHunter2]

I have a Button (the screen language Button which takes multiple children), with a Text and an Image (using "add") inside it. If I hover over the text, the Button's "hovered" action is run, and if I click on the text, the "action" is run. But if I hover over the image or click on the image, it's completely unresponsive. How do I get the button to respond to either of the elements inside it? Isn't that what it's for in the first place?

Code: Select all

    button:
        focus_mask Image("a.png") # non transparent pixels = sensitive

Note: You could also use TextButton and set:

Code: Select all

    textbutton "The Text":
        focus_mask Image("a.png") # non transparent pixels = sensitive
        background ... an image or (often better to auto scale) Frame
        hover_background ... ditto for hover

Using focus_mask as my image means the only sensitive part of the button is the image. Making a custom focus_mask image with a box where the text would be is not possible, since the text can be of arbitrary length. Setting the focus_mask to True or None also does not seem to work (the image portion is still not sensitive), despite what https://www.renpy.org/doc/html/style_properties.html says.

It works fine if using textbuttons and scalable Frames with alpha images for focus_mask and all backgrounds. Never tried it through using button: so cannot really help further.
