I have WordPress Archive view (for a taxonomy) and I wish to have blocks both above and below the WordPress Archive Output. I am able to place blocks below the WordPress Archive Output but not above. In the editor, if I drag a block to be positioned above the WordPress Archive Output it simply vanishes from the editor.
It is important to be able to place blocks above the WordPress Archive Output because when paginating with AJAX, all blocks in the WordPress Archive Output get refreshed.
See image for where I would like to be able to place a block.
I added a custom HTML block (with a shortcode to output a random number so that I could see if it refreshes after ajax pagination) after the WordPress Archive block itself, at the very bottom.
I then used the up button (on the little navigation section that appears to the left of the block when selected) to move the block upwards, expecting that it might move it above the entire WordPress Archive block, but it actually moved it inside the block, directly before the WordPress Archive Output section (screenshot), right where you want it.
(And I can confirm that it doesn't get replaced by ajax pagination.)
