CMS 6 REGRESSION: Can't click-and-drag select title field in inline-editable blocks

[GuySartorelli]

In CMS 6 specifically, if I try to click-and-drag to select text inside the "Title" text field in an inline-editable block, it starts dragging the block instead.

Dragging to select text in the WYSIWYG works. I didn't test any other fields but presumably any input tag has the problem.
