Changing a button's size resets the selected style to the default

[Cheffheid]

When I add a button to the editor, select a style, and then change the size of the button the style of the button resets to the default.

I suspect this might have something to do with the custom Edit implementation inside of /js/block-filters/buttons.js, and might be related to it setting just the size class back onto the button and in the process it strips any is-style-* classes that might already be set.

A workaround is available in that you can set the size first and then the style, so it's not a super urgent thing to fix but it would definitely improve the quality of life of working with buttons in the editor.

Here's a quick gif to help visualize what I'm seeing:
