Mirrored display on Southing-Westing CRS #56802

Description

What is the bug or the crash?

When selecting the CRS EPSG:5513 (S-JTSK / Krovak) (area "Czechia; Slovakia.") the images appear mirrored and rotated 90deg.
EPSG:5513 has axis order as "southing-westing" (left-handed)

This is not happening with other CRSs that are also left-handed, like EPSG:3044 "northing-easting"

Neither with other that are "westing-southing" (right-handed), like EPSG:22281 in South Africa (here the image is rotated 180deg, but not mirrored)

I think the image should not be mirrored, and also be consistent in behaviour among different axis orderings. (if northing-easting system is not rotating 90deg, southing-westing shouldn't. Either 0 or 180. 180 would be consistent with westing-southing used in South Africa)

Steps to reproduce the issue

  1. Add openstreetmap layer
  2. Select CRS EPSG:5513
