Zoomed text node is not clipped with CSS overflow (59br37): Is the third assumption actually reasonable?

[kasperisager]

The rule currently makes the following assumption:

While success criterion 1.4.4 Resize text does not explicitly mention which viewport size has to be resized up to 200%, it is assumed that a viewport size of 1280 by 1024 is applicable. A 1280 by 1024 viewport size is explicitly mentioned under success criterion 1.4.10 Reflow.

When I first read this, I recall my first thought being along the lines of "sure, this seems like a reasonable viewport size for an average desktop display". But then it struck me: Isn't it reasonable to assume that users on mobile devices should also be able to zoom to 200% without loss of content? For example, this is what passed example 1 looks like for me on an iPhone 6 with the text size bumped to 200%:

Going to bring this to the call. The challenge here is that there somehow still has to be a minimum. Maybe 200% on mobile is fair, but is 200% on a smart watch fair? What about even smaller displays? How small does it get? We'll discuss.

We're going to open this with AG. This isn't something the CG can really answer.
