This will require test coverage and a changelog

[dmurphy18]

@ndptech FYI for any PR to be accepted, it requires tests (written using pytest) and a changelog, these were requested a month ago. Are you still interested in continuing this PR ?

A rebase against the latest 3006.x branch would not be amiss too

[ndptech]

@dmurphy18 I am still interested in continuing, but have been very busy.
I'm not familiar with your test suite, and there didn't appear to be any existing tests that were in the same area to use as a base for building new tests - so it may take a while for me to work out what is really needed.
Ultimately there is a fault in 3006.3 and 3006.4 which this patch resolves.

@ndptech Do you mind if I take your PR and run with it, making the changelog and tests for it, and have you review the changes, along with the core team.

[ndptech]

@dmurphy18 That's absolutely fine.

@ndptech This PR is superseded by PR #65524, please review that PR at your leisure and consider closing this PR.
And as I was clearing up my browser tabs, only then noticed the ' quotes, previously only saw the space 🤦 . I actually do have new glasses on order from Zenni Optical 😆
Sorry about that, but please take a look at the changelog and tests written in the other PR, should give idea on how to do it if you have other contributions in the future.
