As an example, here's a testcase with some (admittedly-severe) too-small and too-large web content, with a select-dropdown and a textfield-with-a-datalist in each section.

As you can see, the select dropdown is styled with the rest of the page and is too-small / too-large (which full-page-zoom mitigates), but the datalist is always "regular size", independent of the page's own styling.

Consider:
* In this example, would you really want the regular-size datalist to get bigger in the first section if the user zooms in to make that section readable?
* Perhaps more importantly, would you really want it to get smaller (potentially unusably-smaller) if the user zoomed out to make that section readable / to make it fit on-screen?

As an example of why the proposed solution (of making datalist respond to full-page-zoom) might have some bad/unwanted outcomes... here's a testcase with some (admittedly-severe) too-small and too-large web content, with a select-dropdown and a textfield-with-a-datalist in each section.
