The initial logical size for JupyterRenderCanvas is (0, 0) by default which causes sporadic divide by zero errors with WGPU validation and also creates issues for CI since get_frame() returns blank screenshots and then improperly sized screenshots before returning correct screenshots (I'm guessing until it processes events to resize the canvas?). This changes it so that if a size is specified for the canvas in the constructor, then that size is used for the logical_size in addition to the css width and height. Not sure if we should just change the default size in the constructor from (0, 0) as well.

Thanks! I can also confirm that our tests work again after this change, can we get a bugfix release with this so our CI works again 😄
