[0.18.10] 'selection-tool' shorcut mod does nothing in 0.18.10, no erros visible, works in 0.18.9

[MasterBuilder]

So I've got a mod that adds a 'selection-tool' item, and a shortcut for it.
It's worked perfectly for many versions of 0.17, and worked up until 0.18.9.
Now with 0.18.10, nothing happens when I click on the the shortcut. I've tested with this as the only mod active, no changes.
Did I miss some breaking change in 0.18.10? The strangest part is there's no errors. Nothing in the log either that I can see.

Attached is the mod & a test save.

- Enable wirebox mod, load test.zip
- Click shortcut for "Wire Box Tool". This puts the tool in the cursor. (This is what isn't working in 0.18.10)
- Drag tool across the power poles. Red & green wires will be added to them.

I don't know if this is something I have to fix, or if it's a bug. I have no error or anything to work with to understand what's wrong.

(Log is from 0.18.10.)

Thanks for the report. It's now fixed for the next release.
