glBufferData and glBufferSubData failing in workers when they used to not

**Version of emscripten/emsdk:**
emcc 3.1.8 I am getting the error, while in emcc 2.0.34 it worked fine (I updated and it broke the code)

I am trying to write some basic streaming code and I wrote a test example where a worker would populate the gl buffers and the main thread would render them, everything being properly mutexed. Here is the github link, it is extremely minimal (I tried to make it so, only like ~275 lines), here is the link https://github.com/yosmo78/EmscriptenWebGLStreamingTest

before there was syncronization issues inside the emscripten/webgl calls, in 2.0.34 as mentioned here https://github.com/emscripten-core/emscripten/issues/16404 but now it won't even let me buffer the data at all.

Any thoughts on how to make this possible?

**Failing command line in full:**
`em++ main.cpp -std=c++17 -sUSE_WEBGL2=1 -sMIN_WEBGL_VERSION=2 -sMAX_WEBGL_VERSION=2 -sWASM=1 -O3 -pthread -s PTHREAD_POOL_SIZE=1 -sALLOW_BLOCKING_ON_MAIN_THREAD -sOFFSCREEN_FRAMEBUFFER -sASYNCIFY -o index.js
`

**-v output**
