Hi,

You have that issue because the PiP feature is not implemented for Mac OS yet. On Windows, where the feature is implemented, the preferences are set by default, PiP window can be resized correctly.

Thanks for the report.

Attachment: Bug 1567009 - Remove titlebar=no rule for the Picture-in-Picture player window to allow resizing on macOS. r?mstriemer

With titlebar=no, we were falling into this branch:
https://searchfox.org/mozilla-central/rev/8a63fc190b39ed6951abb4aef4a56487a43962bc/widget/cocoa/nsCocoaWindow.mm#344

and the NSBorderlessWindowMask doesn't allow for resizing. I don't actually think
we need titlebar=no, because with the chromemargin attribute set at
https://searchfox.org/mozilla-central/rev/8a63fc190b39ed6951abb4aef4a56487a43962bc/toolkit/components/pictureinpicture/content/player.xhtml#12

we end up drawing into the titlebar anyways.

So setting titlebar=yes means that we get a resizable window, and it doesn't appear
to effect the window visually.
