Additional context

I'm seeing the same on my Pinecil V2. Issue is not present in 2.22. Issue is present in 2.23rc1, 2.23rc3, and 2.23rc4. All builds tested were from https://github.com/Ralim/IronOS/releases

It looks like this was lost in the refactor:

v2.22...v2.23-rc4#diff-8c50a175baa140c41981bf7da2a97e85d5ac6b25a88b9ee3c2b89fe055ae7e16L40

https://github.com/Ralim/IronOS/blob/v2.22/source/Core/Threads/OperatingModes/Soldering.cpp#L40

v2.22...v2.23-rc4#diff-9e19aca0dc4c0156c58464c504e2c526c6ea2e85155efd23c5876fd2f456c36fR35

https://github.com/Ralim/IronOS/blob/v2.23-rc4/source/Core/Threads/UI/logic/Soldering.cpp#L35

Adding that logic back in fixed it for me:

This is the only code I've ever looked at in this repo (got my Pinecil last week and noticed this behavior while trying out settings), so I don't feel I'm familiar enough to make a PR at the moment. Hopefully this will help someone with an implementation 😃.

Edit: Diff links don't seem to be working well, so I added links to each version in the source.
