When a PCF component is placed on a High Density Header, the control is not rendered. The "init" and the "updateView" methods are not called. This happens only when the user opens the Flyout to edit the header: then the component is rendered.
There is also no text displayed instead of the PCF component. The text is only rendered with OOB components.


The PCF is displayed only with Low Density Header.
Is there a documented limitation that I am not aware of? Is my organisation not on the latest update? Is it a bug?
Best regards,
Diana
