investigate `ui.textScaleFactor` + `browser.display.os-zoom-behavior`
pretty sure it landed in FF102
- FF104: 1777902 don't change the size of system fonts when ui.textScaleFactor is set
- something to read : https://www.askvg.com/fix-ui-scaling-and-large-fonts-issues-in-firefox-103-and-later-versions/#problem_solution
I don't know the reason or purpose behind this, or browser.display.os-zoom-behavior
... just another couple of variables to go with default zoom, zoom text, system scaling, dpi, device pixel ratio, layout.css.devPixelsPerPx
I tested it in FF and it affects newwin e.g. at 110 it opens larger but the inner windows (sans LBing) is out by many pixels. I didn't test LBing, sorry, just making a quick issue to follow up on in alpha 13 - when we can use @ma1 's patches
Without wanting to hamper accessibility, I think we need to look at locking most of these down - IIUIC users should be using system scaling
