I have an experience builder page (ArcGIS Online) with text in the header which links to an anchored window with help information (screen shot below). When I click on the link, the window appears but then disappears again after 3 seconds (consistently 3 seconds). The same is happening for the other two links (Contact Us and Share)
I have the setting to 'Click outside window to close' checked. Screen shot of window settings below.
Am I missing a setting? How do I ensure the window stays open until the user clicks outside the window to close it?
I believe this is relatively new behaviour. It's not something I've noticed before, and I distinctly remember previously having to click out of the window to close it. It is happening both in the editor, and when viewing the published version of the experience builder.
