Walls intersect with lights based on the elevation of last selected token

[strongpauly]

Light rendering is inconsistently determined by selection of tokens.

Foundry and System version: Foundry 9.242 DnD5e 1.5.6
**OS, Hosting, Browser **: Seen on MacOS Electron, and Chrome Ubuntu Linux Hosted

Steps to reproduce:

1. Create a wall with height from top -1, bottom -10.
2. Place a token (Token A) with vision on one side of the wall, with elevation -10.
3. Place a second token (Token B) with vision on the same side of the wall, but with elevation 0.
4. Place a light on the opposite side of the wall - light is rendered as if the wall wasn't there.
5. Select Token A.
6. Move the light - light is rendered as if the wall is there.
7. Select Token B.
8. Move the light - light is rendered as if the wall isn't there again.

Expected Result:
Light sources should be rendered based on the perspective of the currently selected token(s).

I appreciate that this might fall under the "better support for lighting" future idea, but it seems that it might be a bug.
