When using JavaScript or HTML Language Mode, collapsing a javascript array does not work as expected.

Initial state:

When collapsing, notice the bottom bracket disappears:

When copying/pasting the collapsed block, only the top line gets pasted:

If I use Plain Text or JSON Language Mode, everything works as expected:

After pasting, the entire block pastes as I would expect:

Additional notes:

• In JavaScript mode, object collapse functionality works as expected--it seems that only arrays have this issue.
