D20163 is still out for review and hasn’t landed yet, so the master don’t include it yet. You’ll see a story in the transaction timeline like “epriestley closed this revision by committing rPxxxx” once it lands.
It will likely land some time in the next day or two, and will probably be part of the upcoming 2019 Week 7 release on Friday.
If you’re feeling ambitious, you can try applying the patch locally (via arc patch or by downloading the raw patch file) to see if it fixes your issue. However, the review process is normally short, so you can also just wait for the patch to reach master.
