Fixes #148819
When multiple tooltips first merged in 7.7.0, TooltipFeature only had
id
andlayerId
property so the original equality check_.isEqual(features, tooltipState.features)
prevented tooltips from opening that shows identical features. Later releases added new properties to TooltipFeature that broke this deep equals check.This PR resolves the issue by mapping features to just
{id, layerId}
before equality check to ensure those are the only properties that determine equality.
