I have a problem with Firefox Beta 53. It also happens in Firefox ESR 45.
Sometimes when I move tab to new window, the tab title disappears indefinitely.
It happens unpredictably, however, I noticed one specific scenario when it happens

1. Open this url in a new tab:
data:text/html,<title>hello world</title><iframe src="data:text/html,<body onload='document.open()'>"></iframe>
2. Move the tab to new window

Result: The tab title isn't visible
Expected: The tab should display the title

I have tested your issue on latest FF release (52.0), latest Nightly build (20170316030211) and managed to reproduce it. I can see that tab title is missing when tab is moved to a new window.
