• The visual-html dependency has been updated to ^2.1.7. Please verify that the new version is fully compatible with your visual regression tests and that there are no breaking changes affecting the snapshot outputs.

To run individual tests we can use
npx vitest run -t tooltip (basically run only tests that match the describe().

So currently reworked this to use vitest and visual snapshots provided by them.
