Bob: Chromebook seems to always request 5V 2.2A PDO, with Cap Mismatch bit set

Project Member Reported by bleung@chromium.org, Dec 5 2017

Issue description

Chrome Version       : 63.0.3239.70
OS Version: 10032.59.0
URLs (if applicable) :
Other browsers tested:
  Add OK or FAIL after other browsers where you have tested this issue:
     Safari:
    Firefox:
    IE/Edge:

What steps will reproduce the problem?
1. Plug in any PD charger that supports 5V 3A.
2.
3.

What is the expected result?
First request to charger asks for 5V 3A. Does not set Cap Mismatch bit if the rest of the PDOs can satisfy this laptop's maximum power.

What happens instead of that?
First request is always 5V 2.2A, with Cap Mismatch set.

Please provide any additional information below. Attach a screenshot if
possible.

Likely due to PD_MAX_CURRENT_MA setting.
