Dragging pinned tab expands the tab (and moves its position)

[djjd47130]

Scenario: A TChromeTabs control with at least two pinned tabs. Option is enabled to hide pinned tab's text. Ever so slightly click and drag the second pinned tab even just one pixel - and the tab suddenly grows to full size, and switches positions to the far left, before what was originally the first tab. I would expect dragging a pinned tab should remain its original size.

It turns out, this only happens if enabling TabWidthFromContent. If that's disabled, the problem doesn't occur.
