Triangular active tab indicator makes no sense with "Attachments" tab

The little triangular UI element indicating which tab ("Home", "messages", "replies"...) is currently active doesn't make visual sense when used on the "attachments" tab, where a "Images", "links", "videos" selector is inserted above the indicator. In this case it appears to be referring to one of the attachment type indicators rather than to the tabs bar above that.

See attached screenshot.
