Is it possible to resize a canvas after transferControlToOffscreen() in wasm?

[FunnyPixel]

I am cross compiling to wasm a multi-threaded rendering engine. Upon spawning render thread we call emscripten_pthread_attr_settransferredcanvases which is same as calling transferControlToOffscreen() in JS. In runtime a hosting JS code is required to resize the canvas to match a window size requested by the user.

For example,calling this:

var canvas = document.getElementById('canvas');
 canvas.width = 640;
 canvas.height = 360;

Throws:

Uncaught DOMException: Failed to set the 'width' property on 'HTMLCanvasElement': Cannot resize canvas after call to transferControlToOffscreen().

I know we are not allowed to call DOM on a secondary thread (worker) in wasm.I wonder if there is still a way to perform canvas resizing in runtime when rendering in worker and using offscreen framebuffer in C++ or in JavaScript?
