Hi. Yesterday I incorrectly logged an issue on firebase/friendlychat #61 regarding a scrolling issue I experienced while working through that particular code lab. ๐Ÿ˜Š

Would this be the appropriate place to report the issue? ๐Ÿ˜ƒ

Thanks in advance.

Yes. Thanks for the detailed report, @mrkiffie! Either me or @ebidel will look into it.

Looking

This is very bizarre and I'm not entirely sure what is the issue is. It looks like paper-drawer-panel and it's scrim are intercepting touch events in some cases and preventing page content from scrolling normally. Scrolling the page a bit can release that "lock" and allow the <pre> tags to scroll. Scrolling some more, can prevent it again

I've begun porting the drawer/header elements to the new/faster app-layout* elements, and it looks like it also clears up this issue. It would still be good to know the underlying issue and PR paper-drawer-panel, but we'll need the Polymer team's help.

The weird flaky behavior could be related to Polymer/polymer#3784 (comment).
