TPageControl shows wrong position and no text in WinManage.

Software tested: WinManage 1.0 Delphi app based attached (here)winmng.zip
ReactOS version: bootcd-0.4.15-dev-1527-g9587fe1-x86-gcc-lin-dbg

Expected behavior under Windows XP SP3:
WinManage - WinXP - OK.png

ReactOS failing behavior:
WinManage - ROS 0.4.15 - Affected.png

Log:
WinManage - ROS.log

Apart of the inverted color boxes (other ReactOS issue), there is an issue that is exactly the same that Wine have. TPageControl shows wrongly in WinManage, so in every Delphi app I guess. Vertical buttons are wrong, without the text and without the adequate dimensions.

Is this a win32ss issue or win32k?

UPDATE: Link to the Wine's same "no text issue" bug too:
