Sigil of Energy fails to restore endurance

Demonstration:
https://streamable.com/e64fiu

Occurs:

• both in groups/squads and solo
• on any swap during the combat, not just the first one
• in dragonfall, jahai bluffs, thunderhead peaks dragon response mission - 100% spotted by me in these locations
• fighting any type of enemy, from bosses to regular ones

First spotted on 20th, the recording above is from 21st, and I've had it today on 2 occasions as well.
Before 20th I was running a different build, so I can't tell if it's a weapon set issue specifically or not

If your mounting it counts as first weapon swap when you get off it.
