[BUG] Text drag and drop to workspace unreliable

Hi Christoph,

After merging Morphic-ct.1675 and Morphic-ct.1676, it works as
expected, thank you. Without ct.1676 the source workspace is not
updated until it regains the keyboard focus, as described in the
commit message.

Kind regards,
Jakob

Workspaces #1 and #2 from above contain much more text than #3 and fill the whole editing area of the workspace, so this would be consistent.
