Assume you have a (badly-designed) web page whose layout relies on the font size that is being specified in px (11px in the example given). Assume further the user specified minimum font size to be larger (e.g. 16px), resulting in broken page display with overlaps that make things unreadable. (I regularly see examples.)

Now increasing full page zoom factor will result in a larger, but still broken page. This is expected from a "dumb" full page zoom, but contrary to user expectations, as on-screen minimum font size actually /increases/ beyond the value necessary.

It would make a whole lot more sense to readjust minimum font size upon zoom factor change so that the actual on-screen size remains constant and equal to the user specified value at zoom 100%. (This should preferably take place without messing up text-only zoom.) Like this, a broken page could be zoomed up until it displayed correctly (if potentially a bit heavy on scrolling - but at least you can read all the text then), thereby giving the user a bit of extra flexibility in handling bad designs.

Reproducible: Always

Sounds like a good idea.

We probably want to do the adjustment for zoom-in but not for zoom-out.
