Describe the bug
BPMN 2.0 specification available here https://www.omg.org/spec/BPMN/2.0/PDF defines annotation shape on page 71

and in table 12.24

as an open rectangle without a horizontal connector in the middle and in table 7.1 requires that it can only be attached to other elements with association relationship - a dotted line

so the immovable solid horizontal bit in draw.io.BPMN annotation shape is doubly incorrect.

Please remove it and attach a dotted line straight connector.

draw.io version (In the Help->About menu of the draw.io editor):

• draw.io version 24.5.1

Desktop (please complete the following information):

• OS: Windows 10

OK, but you get a lot of fixes, I think users can manage without this one.
