Are you still getting this? I don't see it.

The error happened with custom patch applied, closing.

[notifications] Rework the notifications sizing code

This reworks the notification sizing computation to use Layouts. This
should fix all the popup sizing issues there are (including a binding

Now it also properly elides after max 4 lines of text.
