3.28.0 regression with WFS layers not showing any data

[kommen]

What is the bug or the crash?

A project's WFS layer which displays fine in 3.26.3 doesn't display any data when opened with 3.28.0

Steps to reproduce the issue

1. open this minimal sample project: wfsbug.qgz.zip
2. try do display the data of the Radabstellanlagen layer in QGIS 3.28.0.

The features of that layer are shown in the Attribute Table, but not on the map. The layer doesn't even have a check box in the Layers panel to show it.

This works fine when opened with QGIS 3.26.3.

@kommen thanks for reporting!

This regressed in ec96b49.

The issue is, that with this change for WFS 1.0 there was no GetFeature on one feature anymore to guess the geometry type if we do not know the exact geometry type from DescribeFeatureType:

QGIS/src/providers/wfs/qgswfsprovider.cpp

Line 184 in 5dc2ab9

if ( !mShared->mWFSVersion.startsWith( QLatin1String( "1.0" ) ) &&

Possible fix in #50943.
