Wall vines are destroyed when activating dispensers and droppers after world conversion

There is a world conversion bug that affects dispensers and droppers with wall vines (bug note: invisible wall vines). When I convert the world from Legacy Console Edition to Bedrock Edition, dispensers and droppers with the wall vines are destroyed when activated by any basic redstone component.

Steps to reproduce:

1. Go to Legacy Console Edition, click the play game button, and then click the create world button to start a new world from the play menu. Change the game mode to creative mode.

2. Obtain the vines, dispensers, and droppers from the creative inventory.

3. First, build the wall structure with a dispenser and dropper, and place some torches to prevent the vines from spreading too much (see some images below).

4. Then, cover the dispenser and dropper with both vines (see some images below) and let them spread (vines have a 25% chance to spread).

5. Finally, add any basic redstone components that will power the dispenser and dropper.

6. Exit and save the world and exit the Legacy Console Edition.

7. Go to Bedrock Edition and click the settings button. After almost reaching the bottom, click the "storage” button. Then, click the “storage” button and scroll down until you see the old worlds option. Finally, click if you want to convert your old Legacy Console Edition world to Bedrock Edition.

8. Finally, click the converted world from the settings menu.

9. Check to see if the wall vines are destroyed when you activate the dispenser and dropper with any basic redstone components (bug notes: invisible wall vines and invisible dispensed mobs).

Observed result:

Wall vines are destroyed from dispensers and droppers when activated with any redstone component.

Expected result:

Dispensers and droppers should not destroy the wall vines when activating any basic redstone components after the world conversion.
