Container PostFX Blur broken as of v3.80.1

[vijayrudraraju]

Version

• Phaser Version: v3.87.0

• Operating system: MacOS

• Browser: All

Description

container.postFX.addBlur does not work after v3.60.0.

Originally, I noticed this locally, but it's easiest to confirm with one of the public examples:
https://phaser.io/examples/v3.85.0/fx/blur/view/container-blur

If you switch the version to v3.60.0 using the provided dropdown, it works. Any version after that, it stops working.

Thanks, I am a huge fan of this game engine!

UPDATE: It actually only works in v3.60.0... is this example supposed to work or is this deprecated?
