I think this issue maybe also happens to other links which are on the Quick Docs pane. Just saw this also happening to link flex related to property display.

Doesn't seem to be an issue for some other properties with shorthands (like border), so this might just be a problem with a few cases.

To @pthiess to track for now.

The problem is in www/extensions/default/WebPlatformDocs/css.json

For some reason, in some cases double quotes (") are escaped as " where they should be simply backslash-escaped, as in \"
I changed css.json locally to test this out, changed the links in background's description and it works fine. There are probably other properties that have the same issue.

Sounds very similar to #4342...

Found another links issue today for property animation-timing-function. The links on its Quick Docs pane are also not correct. They redirect to upload picture page instead of corresponding picture. Here is the snapshot:

@julieyuan - If possible please verify if this is fixed.

Checked this issue with build 0.32.0-9586. It still reproduces.
