Description

Projects with inherited forms migrated to D2010 have the following problems:

1. At design time, form sizes are incorrect (smaller than in previous versions)
2. At runtime, autosized elements such as TLabel have an incorrect size.

Steps to Reproduce:

1. Create a new project in Delphi 7.
2. Set the base form's WindowsState property to wsMaximized.
3. Place TLabel and set its properties as follows: WordBreak = true, Align = alTop, AutoSize = True.
3. Create a descendant form and assign its Label1.Caption property a long multi-line text.
4. Make the descendant form as the main application form.
5. Compile and run to see results.
6. Open this project in D2010, compile and run it.
7. Compare the resulting forms in D7 and D2010.

Has this been tested in Delphi XE already? Might be fixed there but nobody yet noticed?
