[Layer properties] Text on symbols group not updated when the layer symbology changes are applied

Author Name: Harrissou Santanna (@DelazJ)
Original Redmine Issue: 18805
Affected QGIS version: 3.1(master)
Redmine category:map_legend

Open layer properties
in symbology tab, apply a new symbology
Click Apply to render the changes in the map canvas and layers panel
Enable the Legend panel: symbols in "Text on symbols" group are not updated, still showing the old setting
You need to reopen the vector layer properties dialog before the symbols get update.

This seems fixed.

This seems fixed.

I'm not sure. In the next gif, you can see that the "Text on symbols" items are not updated until I reopened the dialog

Ah right, I just did ok directly after setting the symbols.

This is still true on QGIS 3.16.14 and 3.22.1.
