Reset to font defaults sets opsz to 16 instead of true opsz default

[Lorp]

For various versions of Amstelvar and RobotoFlex, the "Reset to font defaults" button resets opsz to 16 instead of 14 (the true opsz default).

I believe in the "Ramp" layout it checks the "Mirror size changes" checkbox and then uses the same value as in size (font-size) so arguably the "font-default" would be to use the same optical size as the font-size value (in pt).

"Reset to font defaults" in various browsers, on Roboto Flex (the default font):

• Safari: forces "Mirror size changes" on, sets opsz to 16
• Chrome, Firefox: forces "Mirror size changes" on, sets opsz to 64

It is therefore impossible to perform a true "reset to default". Roboto Flex opsz default is 14.

64 is the font-size in px (not pt) of the first sample. I don’t know where it gets the 16 from in Safari.

I remember the feature being problematic, but I obviously didn't fix it. In TypeRoof Legacy it's even worse from what I remember, I probably didn't port it because of how sketchy it is done here. If I would fix it (at all), I'd rather do it in TypeRoof legacy than here.

From looking at the code: The reset function does the same as when a new font is loaded and that includes setting the "Mirror size changes" checkbox.

It is therefore impossible to perform a true "reset to default". Roboto Flex opsz default is 14.

Yeah, it does not look like what you describe was intended when it was implemented.

Safari: forces "Mirror size changes" on, sets opsz to 16

I don't know why this happens/didn't check.

Chrome, Firefox: forces "Mirror size changes" on, sets opsz to 64

When I have T2 selected and press the reset button, the focus changes to H1 and show opsz 64. When I change focus back to T2 I get ospz 14. But this is not the font-default, it is the same as the font-size in T2
