* Requirements for Android Chrome to apply the system font size to a text inside an iframe:

* - The text mustn't be positioned absolutely;
* - The text block must be wide enough.
* 2560px on some devices in portrait orientation for the biggest font size option (32px);
* - There must be much enough text to form a few lines (I don't know the exact numbers);
* - The text must have the `text-size-adjust: none` style. Otherwise the text will scale in "Desktop site" mode;
*
* Requirements for Android Firefox to apply the system font size to a text inside an iframe:
* - The iframe document must have a header: `<meta name="viewport" content="width=device-width, initial-scale=1" />`.
* The only way to set it is to use the `srcdoc` attribute of the iframe;
* - The iframe content must get loaded before adding extra content with JavaScript;
*
* https://example.com as the iframe target always inherits Android font settings so it can be used as a reference.

* Observations on how page zoom affects the measurements:
* - macOS Safari 11.1, 12.1, 13.1, 14.0: zoom reset + offsetWidth = 100% reliable;
* - macOS Safari 11.1, 12.1, 13.1, 14.0: zoom reset + getBoundingClientRect = 100% reliable;
* - macOS Safari 14.0: offsetWidth = 5% fluctuation;
* - macOS Safari 14.0: getBoundingClientRect = 5% fluctuation;
* - iOS Safari 9, 10, 11.0, 12.0: haven't found a way to zoom a page (pinch doesn't change layout);
* - iOS Safari 13.1, 14.0: zoom reset + offsetWidth = 100% reliable;
* - iOS Safari 13.1, 14.0: zoom reset + getBoundingClientRect = 100% reliable;
* - iOS Safari 14.0: offsetWidth = 100% reliable;
* - iOS Safari 14.0: getBoundingClientRect = 100% reliable;
* - Chrome 42, 65, 80, 87: zoom 1/devicePixelRatio + offsetWidth = 1px fluctuation;
* - Chrome 42, 65, 80, 87: zoom 1/devicePixelRatio + getBoundingClientRect = 100% reliable;
* - Chrome 87: offsetWidth = 1px fluctuation;
* - Chrome 87: getBoundingClientRect = 0.7px fluctuation;
* - Firefox 48, 51: offsetWidth = 10% fluctuation;
* - Firefox 48, 51: getBoundingClientRect = 10% fluctuation;
* - Firefox 52, 53, 57, 62, 66, 67, 68, 71, 75, 80, 84: offsetWidth = width 100% reliable, height 10% fluctuation;

* - Android Chrome 86: haven't found a way to zoom a page (pinch doesn't change layout);
* - Android Firefox 84: font size in accessibility settings changes all the CSS sizes, but offsetWidth and
* getBoundingClientRect keep measuring with regular units, so the size reflects the font size setting and doesn't
* fluctuate;
* - IE 11, Edge 18: zoom 1/devicePixelRatio + offsetWidth = 100% reliable;
