Major From Justin:
"Alan filed a FLUID-6357 the other day when it was observed that the aria-expanded was added to the wrong UIO element on the Inclusive Cities site. This has been addressed in Infusion and I’ve cut a new dev release that includes the fix (3.0.0-dev.20181204T213346Z.2ca90f6e6).
In addition, Antranig mentioned to me the other day that the text was moving on page load in Chrome. This was an issue that he had also mentioned quite a while ago and we also fixed a bug in Infusion that was causing it. However, it doesn’t appear that the instance of Infusion was updated after that. This latest version should address both of those problems."
