Docked block titles are not displayed correctly when docked to the right in RTL

The titles of all docked blocks, when using a right-to-left (RTL) language, are displayed facing outwards when docked on the right. On checking out the CSS, using FireBug, I found they are being rotated 270degs where in actual fact they only need to be rotated 90degs.

Also because we read from left-to-right (LTR) when reading English, we see the docked titles facing us. So tilting the head slightly to the left we read them from the bottom to the top (BTT) This is what RTL languages should do too but on the right-hand side of the screen. So that when reading with your head tilted to the right you would read bottom-to-top just the same.

Currently this is not the case as the titles face outwards and are not easily read.
