Spores Druid multiclass temp HP mechanics?

Would a Spores Druid remain in the Symbiotic State if they recieved temp HP from an alternative source?

I know it doesn't stack but it's said you have to choose between the sources of temp HP.

So for example, gaining it fron killing an enemy in a multiclass like Long Death Monk or Fiend Warlock if the initial temp HP from the wild shape goes lower than the temp HP those options offer.

Would the spores druid remain in the symbiotic state from the top up or would it end due to being from a different source?
