@hhk7734 Thanks for reporting, Assigned to the next bugfix release.

I did remove some code that trimmed these blocks, as part of the last release, since that caused issues with intentional indenting but it looks like we should still trim the end.

A patch has been applied and will be deployed as part of the next bugfix release.
