Support Status: interestfor attribute supported CSS fallback / interestfor attribute not supported

No JavaScript Tooltips with Initial Delay Only

Hover the first one and it waits 200ms. Slide to its neighbours and they open immediately.

Trigger
interestfor on each button, popover="hint" on each tooltip. Hover, focus, or long-press. Hint popovers don't force-hide unrelated auto popovers.
Placement
position-area: block-start with flipping fallbacks
Timing
interest-delay-start: 200ms , dropped to 0s by .grid:has(.tip:popover-open) . One warm-up per visit to the "grid", not one per logo.
Fallback
Without interest invokers, an @supports block does the same behavior off :hover and a registered custom property acting as a warm-up timer.
