As part of #5922 I've removed the code that we had (implemented by @penalosa) that dropped the problematic dispose and asyncDispose properties from RpcPropertys (see here), as I thought that such operations were no longer necessary (and there were no tests showing that removing them was breaking something) but it turns out that they are 😓, so I am reinstating the old code back and adding tests to make sure we don't re-regress on this 🙂

I've been baffled by the same issue for a couple weeks now and the prerelease above fixes it for me 👍
Thank you!

after talking to Dario async, seems like this PR introduces a small regression (see #6235 (comment)). Let's hold off merging it until I discuss this with our team

[dario-piotrowicz]

@CarmenPopoviciu I've refactored the PR and now it's not introducing any regression at all 😄

If should be pretty good to go! 😃

Please give it another quick review if you would 🙏
