sorry but there is no information here for us to act on.

which device?
which version of WebView is your new version?
which version of facebook are you using?

The only thing that comes to mind is this:
https://codereview.chromium.org/2522053002/

but this is very recent.

I believe we have a repro on this, b/33306530

we still need feedback on that. our internal bug seems different.

Effort from the triage Team:
There is no active investigation / updates since the last couple months,closing the issue.

Feel free to reopen if needed.
