Docs: Workaround Chrome Bug

[facelessuser]

Chrome recently made some kind of change that broke our logic for harmony diagrams. We've greatly mitigated the problem from how it was, but it's still there, and it ONLY affects Chrome and may be specific to Mac, not sure.

It seems to be a rendering issue. To mitigate the problem, we had to add a number of unnecessary transform: rotate(0deg). It's a shame because it used to work just fine. Ideally, we could mitigate the rest of this anomaly, but if not, it's not that bad, and this issue can be used to remind us to remove the workaround if at some point the issue is fixed.
