Bug in VSC Webcore: Compiler does not find TPanel, but in fact it's TWebPanel

WEB TMS Web Core VSC
1

Hello!
Using current VSC and Webcore, when opening and compiling an older test project, I get this error:

errVSCWebcore_panel
errVSCWebcore_panel575×932 66.8 KB

The compiler sees a TPanel type, but in fact there is no TPanel. A GREP in all project files does not find TPanel, but only TWebPanel.

So where does this come from?

Greetings, Meik Stoll

What does the DFM contain?

When removing the panel and the including controls and adding back a TWebPanel object, the compiler does not give this error again.
So it's ok now, but it was a bit strange...
