Expected behavior
For stepping on a tripwire that is unconnected from any hooks to have no effect on redstone.
Observed/Actual behavior
On occasion when the tripwire is "triggered" / processes an entity colliding with it (be that a player, mob or item), something breaks in scheduled ticks causing redstone in the same chunk to stop working as expected. This affects not just complex redstone, but something as simple as a redstone repeater clock.
Steps/models to reproduce
Create the following structure, which is a redstone clock **crossing a chunk boundary
**, with a piece of string in one of the two chunks it occupies, and using a torch + redstone block to create the initial clock pulse.
trigger the redstone clock to begin cycling.
step onto and off of the tripwire string (in the red area of the screenshot)
This may take up to a minute from testing for the bug to occur.
You can also use a dispenser to drop items through the tripwire string to trigger the bug.
A vanilla structure schematic of such a device has been added below.

The redstone clock freezes without any apparent external input.
