[Bug]: Tags are duplicated in HTML report

[seanlafferty-ibm]

Version

1.58.2

Steps to reproduce

Have a describe block and a nested test both tagged with the same tag eg

test.describe("@saas tests tearsheet", () => {
  test("@saas create HTTP test using tearsheet", async ({

Expected behavior

HTML reporter should only show the @saas tag once

Actual behavior

saas is here 3 times. Once because its in a project called saas, and then two more times. Once for the describe and then once for the test. I would expect the describe and test tags to be collapsed to one.

Additional context

The tags in the test names already eats up a lot of screen real estate (see #17375) and now showing multiple of the same tag pills eats up even more.

Do I have a usecase for having the same tag in the describe() and test()? Not really, this is just a huge suite with a lot of things that have moved around over the years, so I recognize this scenario may not be all that common.
