Here's the stack:

BrowserOpenAddonsMgr/<@chrome://browser/content/browser.js:6577:7
Promise@resource://gre/modules/Promise.jsm -> resource://gre/modules/Promise-backend.js:390:5
BrowserOpenAddonsMgr@chrome://browser/content/browser.js:6551:10
oncommand@chrome://browser/content/browser.xul:1:1
Flags: qe-verify?
Priority: -- → P2
This stack seems incomplete. I guess the promise in BrowserOpenAddonsMgr is what prevents getting a correct stack. The sync reflow is likely due to the openUILinkIn call (that moves the focus) at http://searchfox.org/mozilla-central/rev/7aa21f3b531ddee90a353215bd86e97d6974e25b/browser/base/content/browser.js#6587 or to the explicit .focus() call 8 lines later.

That's bug 1356858.

I can't reproduce this locally - I think this might have been fixed in the meantime.
