Hi Stephen, do you mind taking a look at this position:sticky bug. I have run a manual bisect on this:

You are probably looking for a change made after 433093 (known good), but no later than 433116 (first known bad).
CHANGELOG URL:
  https://chromium.googlesource.com/chromium/src/+log/a2907993ffbc7f8e21b2dce12c2ff5d541afca7e..c50de9461915f2f19a64ee5105ff885134661810

None of the CLs in the list seems to have caused this.

Note; appears to be compositing-related; removing the following will cause it to move 1px back up:

.ot-car-cursor - remove 'will-change: transform, width'
.pg-tabs - remove 'will-change: top'


yigu - is this another example of  issue 693412  ?
