It is not possible to filter the inline blocks available for placement by the section to which a block is being added.
#2973615: Add Section delta as extra data on filtered block definitions → added the section delta as $extra data on filtered block definitions for non-inline blocks. However, that patch failed to analogously add the section delta for inline blocks. The intent of #2973615 clearly was to affect all blocks (not just non-inline blocks), but that was not the end result so I categorized this as a bug report.
Add the delta for inline blocks too.
