v4.2.22.9 release

Version 4.2.22.9 had five bug fixes.

Significant defects addressed

• Corrected an error that threw a duplicate-entry error message after saving a parent asset that contained one-off child assets.
• Corrected an error that, when double-clicking an enhancement inside the rich-text editor, duplicated the enhancement (along with opening the edit widget).
• Corrected an issue in which restoring an archived asset displayed a confirmation in the content edit form, but the asset was not actually restored.
• Corrected an issue in which the list of tabs in the content edit form (displayed by clicking more_horiz) did not fit inside the widget containing the list.
• Corrected an issue causing editors to click an asset twice in the content picker for it to be added to a selection field.
