Hi @edgiardina! I'ts already reported:

#15512

The suggested workaround with the custom renderer worked for me.

Similar or duplicated #15512

Hey @edgiardina, a PR (#15600) for this is open now, would you be able to grab the NuGet as described here and let us know if this fixes this issue? That will greatly speed up the review process.

Besides verifying if this particular issue is fixed also be sure to check other scenarios in the same area to make sure that this fix doesn't accidentally has side-effects 🙂

Thanks!
