mobile-to-desktop option is negated by feature support

[steverep]

The mobile-to-desktop flag appears to be completely negated by adding an intersection with a feature query. For example:

$ npx browserslist --mobile-to-desktop "defaults"
and_chr 113
and_chr 112
and_ff 113
and_ff 112
and_qq 13.1
and_uc 13.4
android 113
android 112
...

But adding any supports feature query produces different results:

$ npx browserslist --mobile-to-desktop "defaults and supports es5"
and_chr 113
and_ff 113
and_qq 13.1
and_uc 13.4
android 113
...

I get why this is happening since caniuse doesn't keep data on older mobile versions, but it seems to me that the entire point of the mobileToDesktop option is to assume that mobile version numbers act like their desktop counterparts, so this is definitely unexpected and should be fixed IMO.

I will need a help with PR here since I am busy on another project right now
