The mechanic uses their colonial range for actually sharing the institution, so if you are out of range for them, then they can't do it. I guess it's a misleading tooltip issue.

That's correct, but I don't think that that is the problem in this case. I melted the save from the bugreport and several of Imerina's provinces are within colonial range of Mombasa:

I also tested if the capital must be within range, but moving Imerina's capital to the province from the screenshot didn't help. What helped was colonizing the uncolonized province Comoros as Imerina which has a distance of 111 from Mombasa. It also helps to give dip tech 7 to Mombasa so that they have a colonial range of 275. But giving dip tech 7 to Imerina doesn't help which confirms that the colonial range of the other country is used. So I think there is a miscalculation in the colonial range for knowledge sharing. AFAIK the AI gets a hidden 25% colonial range bonus and maybe the game tries to remove that bonus when calculating knowledge sharing, but there is some error in that formula(e.g. the game removes 25% from the range even though the modifier was not included in the first place which would result in a range of 160*75%=120 which is a little below the distance of 129 to the closest province, but above the 111 to Comoros).

Indeed, 160 range is what you have as starting tech 3 in East Africa. They have the same range I do (160), which is still generally accepted to be greater than 133!

It sounds like you may have found the explanation for what the game is doing!

It is still necessary to look from their perspective, because distances in eu4 are not the same in both directions due to trade winds and other weirdness in the calculations. In this case, the distance from Mombasa to your closest province Iboina is 129 while the distance from Iboina to Mombasa is 133.
