(Visual?) Bug with Support gem "Fist of War". +We need doll for DMG Testing!

When I leveled the Titan specialization skill "Ancestral Empowerment", everything was fine. But after canceling the leveling of this skill, the display of the enhancement progress on the bottom skill panel changed (I think before, the charged skill was highlighted in red). In particular, the support stone "Fist of War" was inserted into the skill "Hammer of the Gods". Re-leveling the specialization skill "Ancestral Empowerment" does not help.

Maybe the support gem stopped working not only visually?

To check these kinds of bugs, or just some game mechanics, I suggest adding a doll for damage testing (like the doll in Diablo 4). It would be very useful.
