Tahn Bug - Interaction with Summoner Spells

There is a bug currently where anyone can use a summoner spell that is instant cast that Tahm has while devourered by him (Spell is cast on exit)

How to reproduce:

• 1 Summoner locks in Tahm + one of the following summoner spells on the F keybind:
• Heal, Clearity, Ghosty, Barrier, Cleanse
• Other summoner Locks in any champion + can not use same summoner spell as Tahm on F Keybind

Ingame Tahm Devour other summoner While inside Tahm, Summoner will have to spam leftclick somewhere on minimap, on exit the summoner sinside tahm will use Tahm's D summoner spell, but it does not go on CD.

This can easily be abused and we're some friends who tested this in a custom game with diffrent summoner spells and worked every time with the ones I listed above, Teleport and Flash got the targeting up, but we never managed to use it.

Smite and Ignite works aswell, but harder to hit as you need to target the target on minimap for it to work.
