Raster Legend aspect and behaviour 3.6.13 vs 3.7.8

[Antoviscomi]

Using image as legend in 3.6.13 for a raster layer gives rise to a group with the ability to deactive and hide the layer legend from TOC, that allowed the legend to be hidden like in screencast

In 3.7.8 the management of the legend with use of image has changed so the display is as in the following screencast, with evident disproportion between image and title in addition to the lack of group layer-like management

all settings are the same for project in two LWC versions because of the same directory and the same optional js actived

Steps to reproduce the issue

1. configure a raster layer legend with image as legend from legend settings in qgis;
2. save .cfg via LWC plugin;
3. open the project in LWC 3.6.13 and 3.7.8

I also add that I modified mine map.css according to @nboisteault fix Update map.css #4539, but even reinserting the controls on the layer_tree the results in size does not change

Are they grouped layergroups (both automatic translations are not entirely clear)?

I already noticed the problem with the legend display, especially with grouped layergroups, in 3.7.x (see #4431 and #4382). Another problem with grouped layergroups is that they cannot yet be controlled (active or not) via the QGIS themes. This is a bigger problem than I first thought, as I have grouped quite a few layers. I hope that the behaviour of the grouped layergroups will be revised in 3.7.x.

@guenterw the raster in previous isn't a member of Layergroup but simply a raster in a project.

This seems another issue I've take a look to the discussion #4431 and #4382

In this case the issue concern to the management of raster legend with a custom image in. So in 3.6.13 there is the ability to hide legend (like for grouplayers) in 3.7.8 there isn't, in addition, in case of custom image as raster legend, there is a disproportional size between the Legend and his Title
