What is the scenario where a user would want an invisible tab to start PiP? When navigating to another tab or app, it is convenient to automatically invoke picture-in-picture as occurs on iPad. Undesired launches of picture-in-picture mode would not be likely due to the rules on auto-play media. |
When attempting to initiate picture-in-picture mode with `webkitSetPresentationMode("picture-in-picture")` while the tab is not visible, the following error occurs: `HTMLMediaElement::enterFullscreen(C4262CD8) returning because document is hidden`. While full screen mode should not be allowed to initiate when tab is not visible, picture-in-picture should not be subject to this same rule.
