This needs clarifying. Why do they need that? To create a static image?

LibreOffice imports PDF as a set of graphical objects. PDF forms are means to
provide data to some services. The two worlds don't intersect.

Setting aside the general-purpose PDF libraries supporting dynamic PDF content
(which is natural, given their general-purposeness), Mozilla's decision is
natural (given that opening PDFs in browsers is a norm, and users expect to
interact with such PDFs in a normal way), and is orthogonal to how LibreOffice
opens these files, so this reference is also unrelated.

Again: why? Supporting some "minimal" image-like support for a purely dynamic
feature seems worse than just clear "we do not support it" to me.
