Engi: MDF doesn't proc with all self-sources of healing

The trait MDF (Medical Dispersion Field) in the Inventions trait line states: "A percentage of healing you apply to yourself is shared with nearby allies. "

However, this is not the complete case for all self healing skills/traits. I did a full inspection on most sources of self-healing and posted it in the Engi sub-forum: https://en-forum.guildwars2.com/discussion/40632/mdf-what-works-and-what-doesnt#latest

Basically the following items do NOT seem to proc MDF no matter the situation:

• Healing Turret: Overcharge aka Cleansing Burst
• Medic Gyro pulse heal(Scrapper healing skill, Medic Gyro's "Reconstruction" skill, aka "Gyro Heal" on the skill info )
• Backpack regenerator (Alchemy Trait)
• Heat Therapy (Holo Trait)
• Self application of the Regeneration boon

Test setup:

1. Go into the golem training instance in the Aerodrome with a friend.
2. Equip only the Inventions trait line and select "MDF"
3. Turn on pulsing damage to allow both you and your friend to take damage.
4. For each 5 traits/skills that don't work, equip them one at a time to test. As in, test for the Healing Turret Overcharge and then reset so as to assure there isn't any overlapping.
5. Go through each skill/trait and note that none of the 5 listed proc MDF via the in-game log. Ensure that you and your friend are about half health to ensure that overheal doesn't occur which will prevent MDF from proc'ing in full.

Other requested info:Date, time, and time zone the bug occurred-

• This bug has been around for a while. It is constant bug that doesn't have moments where it does work. Tested in PvP, PvE, and WvW. MDF never works with the 5 items above.

Name of map you're on-

• Occurs in all maps.

Your character name, level, race, and profession-

• Sharak Iskar, level 80, Charr, Engineer(all elite variants). I have tested this on another character engi and the bug still occurs.

Whether you are in a group-

• This bug has happened when I am in a group and when I am not in a group.

Let me know if there is anything else I can do to help with this bug. If there are reasons that the above traits/skills are not supposed to work with MDF, it should be clearly defined in the game.

It really needs to be more clear in the tooltip what does or does not count as self healing.One of the reasons I don't use it more is precisely because I have no way of knowing whether or not it would be wasted in my build or not.
