Branch coloring : do not count tags as branches

Since v18.1 : "The default log coloring now uses adedicated color for each selected refs (unless there are too much)"

This is stunning when having 4-5 branches checked, it really helps the log readability !
But I saw also that if I check the tags then they are counted as selected refs, and the log switch to 2 colors (white for current branch and purple for other branches).

May this count be done only on branches and not tags ?
