Description

Duplicate of (closed) https://github.com/angular/components/issues/4892

MatTooltip triggers with matTooltipTouchGestures set to auto (default) or on break page scrolling on touch devices. When set to either of these values the directive sets touch-action: none on the trigger, which breaks native page scrolling.

On a page with many tooltip triggers (e.g. dense links) it can be difficult to scroll the page at all.

Setting matTooltipTouchGestures to off fixes scrolling, but makes tooltips inaccessible on touch devices.
