Start with the linked StackBlitz reproduction and inspect src/app/dialog-overview-example-dialog.html, then reproduce the jump in Chrome v94 when opening the dialog. Trace the dialog's positioning behavior for the fixed-position element; done means the element is correctly positioned immediately when the dialog opens without regressing other dialog behavior.
