why decodeURIComponent on line 365 and decodeURI here? can we use the same one and share the result?

Let's iterate on this, I need this released faster, and this micro optimization not worth the additional testing effort

[serhalp]

SGTM if you need this hotfixed and you've tested it manually, but afterward could you please add more context to the PR description and consider adding test coverage? 🙏🏼

Request: Once we merge this, can you come back through and add comments that explain the problem and why we're doing what we're doing in this code? And a test, if possible?

The problem is non-obvious from this PR and from the code (I still don't know what the problem this solves is).

[ndhoule]

Oh. Well...what Phil said. 😆

[VitaliyR]

I've added it in the task btw, but I'm planning to put some refactor there, so I will add the comments into the code as well
