popover="hint"

The popover="hint" global HTML attribute creates a popover that is subordinate to popovers with a popover="auto" attribute. You can use this to create tooltips that don't dismiss auto popovers.

Modern Web Guidance

How Modern Web Guidance uses this feature

Displays non-modal, auto-dismissing tooltips and supplemental UI hints with popover="hint" without closing adjacent active menus.

Recommended fallback strategy

For browsers lacking native support, load an official polyfill conditionally after feature detection.
