Print chart in the full screen mode - console error

[Basts]

The error occurs in the console after triggering the print event while the full-screen mode is applied. As a consequence full-screen mode is forced to be disabled but in the export menu the option to close still exists.

accessibility.src.js:431 Uncaught TypeError: a.hasAttribute is not a function
