Cannot use Olroth's Resolve life flask at full HP

Not sure if this is a bug or intentional behaviour.

In PoE1, the way life flasks worked was that they couldn't be used while at full life, UNLESS they gave some kind of other benefit that made sense to use them at full life. An example, if I had a life flask that would remove Freeze effects, it could be used at full life because the ability to remove Freeze is deemed beneficial to be available at full life.

Applying this logic, Olroth's Resolve definitely gives a benefit when used at full life, so current prohibiting behaviour is detrimental to it's use. Unless of course it's for balance reasons.

There exists a bug (or again, intentional behaviour) where you can functionally lower your current life to a decimal point by using Life Tap support. Using this method, your life would not fill by using Olroth's Resolve, allowing the use of the flask while at "full life". This worked for the duration of that instance with a few caveats: 1) Player cannot have any life regeneration, 2) Player doesn't get their HP filled (by leveling up or reaching a checkpoint).

Now after 0.1.1, checkpoints are everywhere, even in maps. I'm sure GGG's intention for adding checkpoints to maps wasn't to brick the above interaction, but it does just that. Therefore, I wish that the restriction where Olroth's Resolve cannot be used while at full life would be lifted, so abusing this unintended behaviour of decimal point HP becomes unnecessary.

Bumping for relevance.

Bump for visibility.

I thought i was going crazy when i tried it and it didn't work.
The use case for this being a proactive instead of a reactive life flask was so obvious it never even crossed my mind they'd make it straight up not work on full hp.

What's the reason to get it otherwise? So i can click heal a little less frequently while I'm getting hit? With the pace of this game I never felt like my life flask was healing me too fast and I'm loosing out on healing due to being full before i get damaged again.

It is really disappointing not to be able to use it on full life, plain flask feel much better than this unique ...
