Tempest Bell interaction with 'Igniting' Fire Spells

Hi all,

I was testing interactions with Fire spells that 'apply an ignite effect' and the mechanic where Tempest Bell gains extra damage of an elemental ailment applied to it.

The pertinent text of each of the fire spells is as follows:

Solar Orb: "Enemies that are very close to the orb are Ignited:
Flame Wall: "Creates a wall of Fire ... which Ignites everything within its area" AND "Any Projectiles fired through the wall ... inflict the Ignite on hit"
Incinerate: "Conjures a torrent of Fire ... Igniting enemies in front of you"

The expected result was that:
1) None of the skills affect Tempest Bell except the burning ground from Incinerate
OR 2) All of the skills affect Tempest Bell

The tested result was that:
Solar Orb and both portions of Flame Wall do NOT affect Tempest Bell.
Both portions of Incinerate DO affect Tempest Bell.

Solar orb and flamewall ignited are both not HITS. Incinerate actually is multiple small hit, which, you know, HIT the bell

Not exactly the topic but close,
I was playing in a group with my mercenary and my friends monk. My explosive shot would ignite his bell and do damage to him when he hit it.
I had to stop using it when he dropped the bell or I would kill him
