The test failures seem unrelated to me. |
There's no guarantee that the onChange callback won't mutate the DOM in some way that removes the selected option node, thus creating a runtime error when null.dispatchEvent is called when trying to trigger the "blur" event on the parent. By saving the parentNode in a variable, we avoid this edge-case scenario.

I saw that a new version was released, so I rebased this PR, and its green now. |
