There currently is no dedicated Sandcastle to reproduce that specific issue. Purely based on the description, it might be a duplicate of #11758 , which in turn, is only a special case of the 🔴-entries of #10480

@MrSmallLiu Would you be able to include a Sandcastle example that replicates the issue? That would help us give us more context to determine the issue. Thanks!
