Hey colleagues,
it looks like the ui5-dialog is not announced as modal when using the header slot:
<ui5-dialog open header-text="Hello World">Content</ui5-dialog>
This is announced as modal.
When using a header slot, JAWS is not announcing the ui5-dialog as modal:
<ui5-dialog open><header slot="header">Hello World</header>Content</ui5-dialog>
Hello @SAP/ui5-webcomponents-topic-rd could you please have a look?
Hello @MarcusNotheis,
I isolate the samples you provided and the both cases the Jaws 2022 announces "modal" when the dialog opens. https://codesandbox.io/s/ui5-webcomponents-forked-2l0pu6?file=/index.html I see no issue here.
Note that for the second case (with the slot) in the documentation there is "Note: If header slot is provided, the labelling of the dialog is a responsibility of the application developer. accessibleName should be used."
Best Regards, Lidiya

Hey there, it's me again! I am going close this issue to help our maintainers focus on the current development roadmap instead. If the issue mentioned is still a concern, please open a new ticket and mention this old one.
hi @MarcusNotheis , I've tested Messagebox with all MessageBoxTypes, and none of it made correct announcement "Modal dialog" after opening. Please kindly reopen this issue and take a look, thanks.
@MarcusNotheis , can you remove the author action label, if you are satisfied with the response?
