As #142465 states, tooltips often interrupt widget interactivity by not allowing events to pass through to the Tooltip child, which is especially poor UX when hovering interact-able widgets on web when the mouse happens to land on the tooltip. I've gone with defaulting ignorePointer to true when a simple message is supplied, since there won't ever be anything interact-able on the Tooltip, and defaulting to false when richMessage is supplied, so it doesn't break anyone's code that has interact-able widgets in the Tooltip. ## Pre-launch Checklist - [x] I read the [Contributor Guide] and followed the process outlined there for submitting PRs. - [x] I read and followed the [Flutter Style Guide], including [Features we expect every widget to implement]. - [x] I read the [Tree Hygiene] wiki page, which explains my responsibilities. - [x] I signed the [CLA]. - [x] I listed at least one issue that this PR fixes in the description above. - [x] I updated/added relevant documentation (doc comments with `///`). - [x] I added new tests to check the change I am making, or this PR is [test-exempt]. - [x] I followed the [breaking change policy] and added [Data Driven Fixes] where supported. - [x] All existing and new tests are passing.
