Apparently, with PNG8 format, selection color do not have alpha value.

Since global image format and selection overlay format can be set
indipendently, a workaround is to set image format to PNG8 and
selection overlay format to plain PNG (that correctly uses alpha
channel).

Selection overlay images are usually small and simple, thus PNG images
are just a little bigger than PNG8 counterparts.
