Selection: Clipboard issues with copy/paste operations on Safari

[boroskoyo]

Description

Two related clipboard problems have been identified:

1. When trying to copy selected blocks using Cmd+C in Safari, a popup appears and nothing gets copied to clipboard. This appears to be related to the copy-to-clipboard package used in the plate-selection plugin.

2. Cross-browser paste operations are not preserving formatting: When copying blocks from Firefox and pasting into Safari, content is pasted as text/plain instead of text/html.

Environment

• Plugin version: 40.2.9
