Improves #13405:

Wasn't sure how to test it first, but then I came up with a reasonable method, see below.

Testing methodology (click to expand)

• grab PR build, extract it fresh
• launch it, enable the IPC server
• restart it, force an update
• before hitting ok to restart, overwrite the files with the PR build
• hit ok to restart, and see what happens

Confirmed on the mainline builds that this is way of testing it still reproduces the issue if present, so should be fine I think.

The more important question is whether or not the pine server still works properly

Good point. Checked with KAMI now and yes, it still does: both status reporting and mouse hooking appears to work as intended.
