JAWS and NVDA on Windows: FAIL
Text inside the dialog is not read at all. Note that the screen reader focus highlight does not move to the words in these sections while the keyboard focus does move. I am able to press space or enter to open more information even though the screen reader isn't saying anything. Buttons are read as expected.

Mac + Voiceover FAIL
Text and section names are not read, VoiceOver only says "You are currently on a text element." when focus is on the order information. Buttons such as Pay and Cancel are both read and word as expected.

TalkBack on Android: PASS but not ideal
All text in dialogs is read in both basic and Bob versions. Buttons are read as expected.
After expanding the Order summary text, TalkBack says "double tap to activate" at the end even though double tapping does nothing. It also says "double tab to activate" after each text section. This should perhaps be replaced with clearer text like "double tab to expand".
