[Bug]: Server tile cache leads to measurement and edition errors

[ppetru]

What is the bug?

My project uses a raster base layer. When enabling the server tile cache for that layer, the Lizmap measurement tool produces ridiculously large values (e.g. hundreds of km instead of <5m) and editing any feature attribute causes them to be teleported far away even if the geometry was not modified by the user.

Steps to reproduce the issue

1. Go to Lizmap QGIS plugin -> layers -> my raster base layer
2. Disable 'Single tile' and enable 'Server tile cache'
3. Save the project and load Lizmap
4. Measure any distance and note result being 5-6 orders of magnitude wrong
5. Edit the attributes (but not geometry) of a feature from another layer. Note that the feature is teleported far away -- its geometry also got modified and is now very close to the center of the CRS coordinates (using EPSG 3763).

• I have done the step just before in the Lizmap QGIS desktop plugin before opening this ticket. Otherwise, my ticket is not considered valid and might get closed.

QGIS server version, only if the section above doesn't mention the QGIS Server version
