1. Confirm there's no leaking in dreev's dev env for any of these bb files
2. Confirm replicata

HT shanaqui who screenshotted this on one of their goals in the wild:

Replicata

1. Create a new odometer goal with a starting value of 10 and rate of 1/day
2. In the graph editor (static or dynamic), add a 2nd graph matrix row with the same date as tini and a value of 20
3. Edit the final segment to continue at a rate of 1/day until an end value of 100

See leaky-yellow.bb in privatesuite. I can replicate this in production (both in pure-Beebody with the static editor, and in graph.beeminder.com) but not locally in dev.

UPDATE: also yellow_shading_wrong_side.bb

Things Nicky checked: rebraining doesn't fix, refreshing doesn't fix, incognito mode doesn't fix, logged in or out doesn't matter, admin or not doesn't matter.

Verbata: graph aesthetics, baneful bugs, leaky shading,

Another example -- leaky-yellow2.bb -- that leaks yellow in production (but not in dev):
