Caolán McNamara d2ecb53639 cid#1500679 Resource leak in object
to reproduce this in reality, insert a chart, activate it, select and
copy and paste something like a bar of a bar chart. Select that copy and
copy to clipboard again. reactivate chart, paste that element into the
surrounding spreadsheet, select and copy something else to clear the
chart transferrable and the model created by the chart transferrable
leaks.

there are an unrelated blizzard of a11y mutex deadlocks here btw :-(
