Incorrect map viewport / aspect ratio on Android Auto portrait display (Renault Zoe Easy Link 9.3")

ABRP does not correctly size the map viewport when running through Android Auto on the 9.3" portrait Easy Link display in a Renault Zoe ZE50.

Android Auto itself uses the entire available screen correctly. ABRP also renders UI elements outside the small map area, which indicates that the application has access to the full Android Auto surface.

The map itself, however, remains constrained to a small landscape-shaped rectangle instead of adapting to the available portrait area.

Expected: The map should resize to the available Android Auto map area and use the available vertical space.

Actual: The ABRP UI uses the available screen, but the map viewport/canvas remains limited to a small landscape area.

Other navigation apps such as Google Maps render correctly on exactly the same Android Auto setup. This therefore seems to be specific to ABRP rather than the Android Auto resolution or the Renault Easy Link display.

Already tested: Android Auto automatic resolution negotiation, different forced resolutions, phone rotation/auto-rotation, and disconnecting/reconnecting Android Auto. None of these changes the ABRP map viewport.

Environment: Renault Zoe ZE50 · Easy Link 9.3" portrait display · Android Auto · TCL Android phone · current ABRP version

From a technical perspective, it looks as if the ABRP map renderer is using incorrect or stale viewport/canvas bounds, or assumes a landscape aspect ratio instead of updating to the portrait Android Auto surface dimensions.
