It is better to use (org-element-property :parent (org-element-at-point))

You shouldn't extract properties this way. See below.

It is better to use (org-element-property :begin parent)

>             (set-mark (point))

It is better to use (org-element-property :end parent)

Anyway, I suggest to use `org-up-element' and `org-mark-element'
instead.
