[Bug]: Layer stack order Firefox versus Chrome

[manogenam]

What is the bug?

I set on Qgis a specific layer stack order. It works with Google Chrome but not with Mozilla Firefox.
Layers are sorted in order of appearance in the layers panel instead of the enabled option.

Steps to reproduce the issue

1. Enable layer order on Qgis
2. Set a different order between the layer order option and the layer panel
3. Save project and publish it

I think it's unfortunately a known issue about the compatibility with OpenLayers. It will get fixed with an update from OpenLayers in our stack.

We will have a few components updated to latest OL 7 in the next release LWC 3.7 and it should be fixed. All the layer tree has been refactored with OpenLayers 7 in the next version of Lizmap.

Might be fixed with #3656

@manogenam Can you try with the new 3.7 release ?
Or can we change the milestone ?

It is now fixed in Lizmap 3.7.
