MC-190815Shulker boxes don't conduct redstone when open, but don't trigger redstone updates when opened
Shulker boxes don't conduct redstone signals when open. However, they don't trigger redstone updates around them, causing redstone components to not react to the changed conductiveness of the shulker box.
To reproduce
In this contraption, the redstone lamps don't turn off when a shulker box is opened:

Shulker box conducts power when open
A shulker box conducts a redstone signal regardless of whether it's open or not. This is inconsistent with previous behavior, where the shulker box would only conduct power when closed.

before 1.20 open shulkerboxes were non conductive. The powered components required an external blockupdate to get depowered as mentioned in this bug report (MC-190815) but now components are always powered
I'm unable to find any difference between the behaviour in 1.15.2 and 1.16-rc1.
The redstone lamp only realizes that it's no longer powered once it receives a block update; when the shulker box opens, it doesn't give an update to other blocks around it. I believe that's your issue; I'll rewrite the ticket accordingly.
Here's a video in 1.15.2 – Minecraft 1.15.2 - Singleplayer 2020-06-21 11-08-02.mp4
Can confirm in 1.17.1.
since 1.20 they dont even depower at all so open shulkerboxes are still conductive. probably not intended?
