Shader translation error for wgpu shadow/water examples with GLES backend

[victorvde]

Since wgpu commit "Remove block decorations", running

wgpu$ RUST_LOG=WARN WGPU_BACKEND=gles cargo run --example water

gives

[2021-12-19T15:14:10Z WARN  wgpu::backend::direct] Shader translation error for stage VERTEX | FRAGMENT | VERTEX_FRAGMENT: error: declarations for uniform `_group_0_binding_0` are inside blocks `Uniforms_block_0Vertex` and `Uniforms_block_0Fragment`
[2021-12-19T15:14:10Z WARN  wgpu::backend::direct] Please report it to https://github.com/gfx-rs/naga

Similarly for the "shadow" example. Last tested with wgpu commit 54f20b / naga 0.8.
