EntraID portal UI updates affecting visibility of proxy addresses

I have an open support case (TrackingID#2608010010000071) but the support engineer also recommended I post here. A recent update to the EntraID portal UI has implemented a stylesheet with a really tight rendering box around the list of proxy addresses that can be viewed from the flyout panel on an identity's account. The result is proxy addresses are being truncated after just a few characters making it very difficult to view the list of valid email aliases for an identity.

I've confirmed, using DevTools to inspect the source data, that the full addresses are being sent to the client. It is the tight rendering box (120 pixels) that is causing the truncated display. If I override the style sheet to use a larger "width" value I can force the display of the entire proxy address.
