[mediaqueries-5] Should aspect-ratio evaluate to false when one side is 0?

[cdoublev]

For example, when the user resized a vertical browser panel that covers the entire viewport, the aspect ratio resolves to Infinity but users might expect it to evaluate to false.

@media not (aspect-ratio) {
  .animated {
    animation-play-state: paused;
  }
}

Chrome always evaluates aspect-ratio to true when one side is 0, Firefox evaluates it to false when the viewport width is 0.

When written like [(color)], the media feature is evaluated in a boolean context. If the feature would be true for any value other than the number 0, a <dimension> with the value 0, the keyword none, or a value explicitly defined by that media feature to evaluate as false in a boolean context, the media feature evaluates to true. Otherwise, it evaluates to false.

aside: I would also add no-preference and a function resolving to one of these values (eg. calc(0), var(--feature)) to the list of the "falsy" values.

I think this is what we resolved in #8244

aspect-ratio queries are always true (except when it can't apply at all)

Ah, sorry. I searched for mediaqueries aspect-ratio in the title.
