Mac: Fix a crash in bookmark manager.

Mac: Fix a crash in bookmark manager. When bookmarks are dragged from
the bookmark bar, the relevant information is stored in PasteBoard. We
were using very old Firefox code to write the data to Pasteboard, which
included the title/url of the bookmark, but not the profile. I updated
the logic to use our new code.

Ensure that composited bubble windows with size less than 64 x 64 don't show up as clipped.

We have code which expands the window sizes to be at least 64 x 64 to work around problems with some GPU drivers in displaying
windows smaller than this. When bubbles are created they are centered using the parent window size and the actual size
which causes them to show up in the wrong place. We need to use the expanded size while centering them. This fixes the position
and also the clipping. Unclear as to why they are clipped.
