FF57 browser.windows.create() displays blank popup window

Add-ons addons.mozilla.org

Hey add-on developers:
My add-on calls browsers.windows.create() api to display a popup. However after the recent FF57 updates, the popup shows up as blank. I have to either right click or drag&resize the popup for it to display the content.

Basically, this does not work correctly anymore in FF57:
browser.windows.create({
‘url’: ‘my-popup.html’,
‘type’: ‘popup’,
});

Currently I’ve seen this issue on WIndows7, Windows10, Ubuntu(14.04.5). However, the problem does not appear on MacOS(High Sierra).

Does anyone know if there is filed bug tracking this?

Thanks
