Description:
Using the latest 6.3.7 client. When pressing 'delete selected rows' causes mysql workbench's CPU to spike; and the application becomes unresponsive. I have confirmed this issue on 4 mac os x laptops (El Capitan & Yosemite).

How to repeat:
Select the contents of a table; select * from blah.

Press the 'delete selected rows'

The application will stop responding.

Suggested fix:
'delete selected rows' should remove the row and await a commit/apply.

I am haveing the same problem with MySQL workbench 8.0.12
when i select multiple rows "huge number of rows" to delete the app hangs and it remain that way for minutes or hours depending on how many rows i choosed to delete.
i am working on windows 10 x64 with the following machine spec:
Xeon x5670 [12 Cores/24 Cache], RAM: 88 GB, x4 SAS [total of 60K RPM]

i never saw the app consume more than 500-600MB of RAM and 0.5 to 1.5 of the CPU even though as i stated i have planty of spare resources..

i will be glad to submit more info if you need any.
