Textfield shouldn't be part of screenreader output

[A11y_Luke]

Hello,

I want to create an acessible form PDF with InDesign (Version 17.1 x64) and I think I've found an PDF-export bug.

Structure of my InDesign document from top to bottom (see screenshot 1):

• Text input field (Description: "Testdescription")
• Text frame with a simple paragraph (Content: "Hello")
  

The text frame is part of an article (Article 1) but not the text input field (see screenshot 2).

My other settings in InDesign:

• I've activated the article option "Use for Tagging Order in Tagged PDF" in article pannel options
• For PDF-Export I use File > Export > Filetype: Interactive PDF

For export I use following options (see screenshot 4).

You can see the structure of the final PDF in screenshot 3.

With this setup for screenreaders like JAWS or NVDA should just read only read "Hello" (= content of text frame and the only content of Article 1). But with screenreaders JAWS and NVDA I get the spoken output "Hello inputfield Testdescription".

I don't know why every screenreader includes the text input field in spoken output because the text input field is not part of Article 1.

Is it a bug or what I'm doing wrong?

Thanks so much for your help!

And this is my final PDF document
