fix: JS InputTable test failure and race

[niloc132]

This test was slightly racy, able to fail other unrelated tests in some situations.

Follow-up to #5600

Looks good, just curious for learning purposes, was there a reason for separating the test cases and then having multiple connections, instead of having the one big connection with a ton of .then() 's like we had discussed on slack?

[niloc132]

Nope, either would have worked, this was quicker than stitching together the promises. The important thing is that each test method only finishes once.

Ah, that makes sense, thanks!
