Tab Order: Storyline skipping first object on non-base layers?
I'm using Storyline 360 v3.26.18601.0 and am having a problem with the tab order.
It appears that when I open a layer from the base layer and hit the tab key, I do not go to the first object listed in my Tab Order panel for that new layer. Instead, Storyline skips the first thing listed in the tab order and goes to the second object in the list. I then have to tab through the entire rest of the page before I am cycled back, finally, to that first object.
Of course, this completely messes up the learner experience since I get to the Next or Continue button before I get to the main content on the page.
Here is a concrete example:
Main Storyline edit screen:
This is a screen from an emergency management course in a module on responding to an earthquake. It consists of a base layer called Drop Cover and Hold On and three feedback layers, one for each of the highlighted regions on the slide. Two are incorrect feedback layers (No: Boxes and No: Bottles) and one is the correct feedback layer (Yes: Good Choice).
The idea is the learner clicks one of the highlighted regions, and in response, a trigger shows the feedback layer associated with that choice. If the learner clicks the correct place to drop, cover, and hold on, then the Yes: Good Choice layer displays:
This layer is set to Prevent the user from clicking on the base layer in its properties panel:
This prevents objects on the base layer from being tabbed to while the learner is on this layer. Also, every object on this layer is hidden from the accessibility tools except for the feedback text box and the Continue button.
Here's my Tab Order panel for this slide:
Here's a Peek video screencast of me trying to navigate through this page using the keyboard only (i.e., navigating with the Tab key and selecting with the Enter key):
The little teeter-totter video clip (meant to suggest the earthquake) at the start of the page in question didn't get captured too well by Peek, but otherwise the video shows the tab behavior quite well. Why does it skip the feedback text box?
Is anyone else experiencing this or am doing something wrong?
