[QGIS-Developer] Not saving new color scale

[matteo]

Hi all again,

with QGIS 3.8 and also 3.9 (compiled some days ago) it seems not
possible to get a saved color scale in the list.

Example:

* create new color scale
* creating a default one or also taking one of the cpt-city catalog
* QGIS takes the desired color scale to make the symbology
* the new color scale is not listed in the list of the color scales

I think this could be a bug, but not sure if this is the default
behavior or if something is changed in the default behavior.

If confirmed I can open a ticket

Cheers and thanks

Matteo
