a!headerContentLayout fixed header doesn't work in Dialog box

Question

We have created an interface using a!headerContentLayout() with isHeaderFixed: if(a!isPageWidth("PHONE"),false,true) and it works great if you are simply on the page. But if you use it in a Record Action with a Dialog box the Fixed Header does not work. Is there a way to fix this?

I don't think so. 
 For the Record, Appian recommends using form layouts for Record Actions in Dialog mode.

There are design considerations when using Header Content layout such as 
 1. If pane layout is used for contents, isHeaderFixed is not considered. 
 2. If fixed header is selected in the header content layout, but it isn't selected for the record header, neither header will be fixed 
 In your case, may be 2nd one applies. So configure the record header similarly and your issue should resolve. Will be additionally good to understand the component properly by following the consideration given in documentation . If record header fixing is not desired then as Mathieu suggested choosing a different layout will be better.
