Compare Multiple Schemas - 'Send script to Editor' button doesn't send updated scripts to Editor (4243079)

When selecting items in the "Compare Mutiple Schemas" results, if the Difference Details tab is selected, the "Send script to editor" button only sends the correct script to the Editor the first time. When (de)selecting other items in the same schema again, if you press the same button again, it sends the previous script to the editor again. As if the script isn't being recreated / updated with the newly selected items.

Steps to replicate:
1. Run a comparison that will have some results.
2. In the "Difference details" tab in the lower panel, uncheck everything apart from one difference.
3. In the results upper panel, click the "Send selected sync scripts" button in the top panel - only 1 difference is sent to the Editor.
4. Now go back down to Difference Details again and change something, check something additional or uncheck everything. In the top panel, click the same button to "Send selected sync scripts".  Notice the one difference from above (step 3) is sent to Editor. The script does not update.
