remember picture,overlay with page anchors not working in ConTeXt LMTX

[ghost]

Brief outline of the bug

As the title says, remember picture, overlaywith anchors as current page.south east is not working in ConTeXt LMTX, when it does perfectly in MkIV. Tbh I don't know if the bug comes from anchors, remember picture, overlay or both. See: https://tex.stackexchange.com/questions/580523/fading-gradient-background-color-page-in-context-with-tikz

<argument> \hoffset

    \relax \global \pgf@y =#2\relax

    \global \pgf@x =\pgf@x \global \pgf@y =\pgf@y }

<macro> \pgf@shape@interpictureshift ...current@pos }\advance \pgf@xa by-\pgf@x \advance \pgf@ya by-\pgf@y \pgf@process {\pgfpointorigin \pgf@shape@original@pos }
    \advance \pgf@xa by\pgf@x \advance \pgf@ya by\pgf@y \pgf@x =\pgf@xa \pgf@y =\pgf@ya \fi 

<argument> ...ikz@pp@name {current page}\endcsname }\pgf@pos@transform@glob }\pgf@shape@interpictureshift {\tikz@pp@name {current page}}

Minimal working example (MWE)

\usemodule[tikz] %using t or m makes no difference..
\starttext
\tikz[remember picture,overlay] 
\shade[top color=green!30, bottom color=blue!30] 
(current page.north west) rectangle (current page.south east);
\stoptext

LMTX is currently not supported because it removed too many primitives.
