Issue with Align on MacOS

Hello, some components like WebChatBox and WebMemo are not shown correct on Form Designer when property Align set to 'alClient'.

It seems like the HTML head causes this problem, any idea about how to fix this issue??

Hi guys, any idea about that??

The part of the HTML template is disturbing the classic control layout with alignment.
If you use a HTML/CSS driven layout, it is better to control positioning of elements via CSS.
