Shape 'lr-tb' vs. shape 'tb-rl'

Open attached document. It contains two shapes with same geometry. The enhanced-geometry has an attribute
draw:text-areas="0 16200 16200 21600 0 5400 5400 21600"

That defines two rectangular areas given as left-top-right-bottom. The second one has to be used, if the text style has an attribute style:writing-mode="tb-rl". That is the case for the right shape.
For definition in ODF see above link.

The left shape has to use the first text area 0 16200 16200 21600, which is a rectangle with width 16200 and height 5400 and left-top corner 0|16200.
The right shape has to use the second text area 0 5400 5400 21600, which is a rectangle with width 5400 and height 16200 and left-top corner 0|5400.
Error: The text with east Asian writing mode 'tb-rl' uses the same text area as the text with 'lr-tb' writing mode.

Yes, the vertical text uses the wrong rectangle. I have now attached a file, where I have added rectangles to show where the text should appear. The blue rectangle indicates the text frame to be used for lr-tb writing-mode (Latin text) and the red rectangle indicates the text frame to be used for tb-rl writing-mode (East Asian text).
