Alternative Text in a Text Box Object

I’m currently using Storyline 360 (Build 3.101.34925.0) with the AI upgrade. While reviewing a text box object (via right-click > Size and Position > Accessibility), I noticed that the Alt Text field is auto-filled with the entire contents of the text box. I don’t recall this behavior in previous builds, and I find it odd that the full text is inserted into the Alternative Text field, especially since that field has a 150-character limit. Additionally, the “Object is visible to accessibility tools” option is checked by default, but I believe I need that checked to have it show in the Focus Order. The inserted text appears in a lighter shade, and when I try to remove it, it simply reappears after I close and reopen the Accessibility window.

Interestingly, when I check the Focus Order, the Alt Text field remains empty. I do have Text-to-Speech enabled on these pages, but I’m not sure if that’s related.

Is this a new behavior introduced in the latest build or possibly tied to the AI upgrade—or am I just imagining things?
