Is this TMS WEB Core v18.104.22.168 you're using?
Yes, I have v22.214.171.124
I cannot reproduce a problem.
Yes I think so. You mean that it's not per-parent as with Win32 apps.
There are several issues in your test project.
First of all, your login username & login password controls use the ElementID which is intended for coupling the control to a HTML element in the HTML form template. When there is coupling, it is intended that attributes are set via the HTML element in the template and not the Pascal component on the form. (HTML controls in this case UI)
Secondly, there are several other controls on the form that have TabStop=true with TabOrder=0, so there are duplicates for TabOrder=0.
Thanks for the feedback.
TWebPageControl did not properly use TabStop: this has been fixed
