Demo: https://www.scirra.com/labs/bugs/safaripointerevents.html
Look at console messages while following these steps:
1. Press down left mouse button and hold it
2. Press down right mouse button and hold it
3. Release left mouse button
4. Release right mouse button
Observed result:
The sequence of events is pointerdown, pointerdown, pointerup, pointerup
Expected result:
The sequence of events is pointerdown, pointermove, pointermove, pointerup. This is how it works in Chrome and Firefox.

Hi Ashley. What version of Safari is this? This should have been handled by the fix for https://bugs.webkit.org/show_bug.cgi?id=198462, which landed after the cutoff for the last Safari Technology Preview build. Alas, I don't actually have a mouse handy to try this out, but this bug was specifically about the correct support of chorded mouse interactions and the Web Platforms Tests work as expected.

Oh, I see now this is STP 85. Could you try with a recent WebKit build? See https://webkit.org/build-archives/.
