Switch Cannot correctly move cursor upward on right-side action buttons after trading item between chest and inventory

OS/Platform: Switch
Switch control mode : Handheld
Game version : 1.6.9 build 36
Game language: English
Game Mode : Singleplayer
Severity: Minor/Bothersome (existing workaround)

Issue :
  • Affected system : Chests & Inventory
  • Symptom: The 'hand' cursor cannot be moved upward (either through left stick or directional buttons) between the right-side button sidebar action buttons "Add to Existing Stacks" (3rd button) and "Toggle Color Picker" (2nd button)
  • Triggering : After trading an item between chest and inventory (regardless of direction - tested both, both trigger the issue)
    • Re-occurrence: 100%
  • Workaround: Moving directly to "Toggle Color Picker" (2nd button) from the chest's inventory's first row and moving down to "Add to Existing Stacks" (3rd button) seems to re-set the sidebar to a working state, and the cursor can be moved freely up and down. (Up until trading an object again, at which point the system goes back to its faulty state and the "wall' is back)

Notes (and troubleshooting idle musings):
  • The issue doesn't persist if the chest-interface is closed and reopened, even if it was closed in its faulty state.
  • The second step of the walkaround (move down and 'break the wall', so to speak) is necessary - moving to "Toggle Color Picker" and going back to the inventory keeps the system in its faulty state
    • So my first guess (two overlapping sidebars, one containing all 6 buttons and another containing the bottom 4, switching Z-order on activation) is probably invalidated (I know code, but next to nothing of SDL, admittedly)

Sub-issue :
When on the Golden Scroll/Community Bundle button (1st button), moving left moves to the top left spot of the player's inventory.
Given the behavior of the same action (moving left) on all other five buttons (2 ColorPicker/3 AddToStacks/4 Organize -> top left of chest inventory, 5 Trashcan/6 OK -> top left of player inventory), and the position of the Golden Scroll button, I would have thought he'd behave like the former, not the latter.

Is it the expected behavior?
