"Minimum font size" does not work?

[pthfdr]

I am using Anonymous Pro for all the pages due to it had embedded bitmaps at small sizes.
I have set the font size to 9 and the minimum size to 10, to ensure that it is using a 10pt font (except very large text like captions).

This is how Chromium handles it at 50% zoom, which is desired.

I used the following CSS to force Chromium to use AP:

Code: Select all

html *{line-height:1em!important;margin:0;padding-bottom:0;font-family:Anonymous Pro!important;max-width:none}
table{padding:0!important;border-spacing:0!important}
video{margin:auto}
hr{margin:0!important}

This is how PM handles it at 100% zoom.

It is only that size at 100% zoom.

This is how PM handles it at 50% zoom. The layout (arrow sizes) is what I desire, but the text is unreadable despite I have set a minimum font size.

Basically Minimum font size does not work.
EDIT: It looks like the minimum font size is relative to the zoom level. I set it to 20 and it works.
