Description
Importing a script or sprite from the backpack can leave its variable inputs blank, and variables used without a set/change block are not imported at all. Reported 2026-06-11 on iPad (iOS Safari), after the 2026-06-01 backpack de/serialization fix (scratchfoundation/scratch-editor#554 and scratchfoundation/scratch-editor#555), so it may be a residual case that fix did not cover; verify against the current build.

Research direction
Start by reproducing backpack import in the current build on a script or sprite with variable inputs, including variables used without set/change blocks. Review the backpack de/serialization changes referenced in scratch-editor#554 and #555, then verify that inputs remain populated and all referenced variables are imported.
