I have been unable to reproduce the error using standard objects in 9.5.4 with a page include in a master page having a date selector.
I’m sorry. I was hoping to be able to see it quickly and easily.
A few questions for you:
When you say you previously updated the themes to no avail, do you mean that the update didn’t work or that the update worked but didn’t resolve the issue?
What browser are you using? Windows or Mac?
I have multiple repro pages that I could provide the XML for. However, it is multiple pages. However, you’d have to rename it and all that jazz. It would likely be easier for you to recreate a basic page trying to reproduce the issue with as simple a page as possible and then see if it fails.
