Headers TFS 2012 missing
We are using TFS 2012. When opening a Product Backlog Item, the header text and the button bar are missing. In Chrome it works as expected.
Vivaldi 1.7.735.46 shows:
and Chrome 56.0.2924.87 shows:
Looks quite different.
I guess Microsofts product uses a faulty browser detection.
Try to change the Useragent to Chrome 56 in Network settings of Vivaldi's Developer Tools or install a UserAgent switcher extension from https://chrome.google.com/webstore/search/agent.
Tried it with user agent at Chrome or IE11, but that does not make any difference. I tested some more and it appear that the problem does not happen at every backlog item. When the problem happens it shows this error in the console:
This same backlog item does show correctly in other browser
Please don't use screenshots for such console errors. Most of them are not easy to read!
