Re: [csswg-drafts] [css-fonts-5] Text Fitting: Default scaling limit (#12886)

Issue Summary for January F2F

**Problem**:
If a container's width is dependent on the viewport width, increasing the page zoom level may not increase the rendered text size because the container's physical width remains unchanged. This behavior fails to satisfy WCAG SC 1.4.4 (Resize Text).

**Proposed Solutions:**
* kizu: Limit the font-size scaling factor for fitting to a maximum of 200% by default.
* Google (bfgeek, chrishtr, tkent-google): When a page is zoomed in, user-agent starts the layout process with the font of which physical size is _max(\<post-fit font-size in 100% zoom level> * \<page zoom factor>, \<computed font-size> * \<page zoom factor>)_.
