Consider improving the design for partially supported browsers in compat tables

Summary

Consider the following compat table:

which you can see at https://developer.mozilla.org/en-US/docs/Web/API/Popover_API#browser_compatibility

I was discussing with a colleague of mine, and we agreed that at a quick glance, it felt like the feature was supported everywhere just fine.

The reasons for this are:

The version numbers all seem to be the same color (not to mention that some folks can't see subtle differences between colors).
The partial support icon doesn't feel super clear.

Reproduction steps

Go to https://developer.mozilla.org/en-US/docs/Web/API/Popover_API#browser_compatibility
Look at the browser compat table.

Expected behavior

I would expect to visually see the lack of complete support on Safari for iOS much more clearly/quickly. It takes me a minute to scan the results and figure out that, oh, it's actually not supported fully on Safari for iOS.

The problem with partial support is that in some cases a minor part might be missing and I can use an API just fine, but in other cases (like this one, where popovers don't dismiss on backdrop touch), I can't reasonably use the feature at all.

Compare to caniuse.com:

I find that it's easier to see the difference between full support and partial support here, because:

there's more of a gap between the two background colors
the additional stripe pattern helps differentiate as well
there's a little square with the number 1 in the cell that helps too

Also, consider the Baseline banner at the top of the page:

The icon for Safari is much clearer about the lack of support.

Actual behavior

On MDN, the visual difference between a fully supported and partially supported browser is a bit too subtle, and the icon doesn't fully convey the status.
