That's the same number of errors on main, so at least we're not creating new ones!

Thanks for raising a PR @yigityuce 🙏

Can I ask you do to add an end-to-end test for this to ensure we don't regress on this? I recommend to look into test/karma/test-app and add a new slot-XXX folder and copy your example from the reproduction case.

Let me know if you have any questions or if I can assist you.

@yigityuce Nope 🙂 I want to land some other infrastructure work to test this out a little more with the Ionic Framework before we land this, but plan on taking a look at the PR itself later today
