Is it possible to filter integer texture in WebGL?

Question

I have read other posts (for example this) that shows how to render integer texture (R16I) via WebGL.

However, it is using the gl.NEAREST for texture filtering for minification and magnification

gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MAG_FILTER, gl.NEAREST);
gl.texParameteri(gl.TEXTURE_2D, gl.TEXTURE_MIN_FILTER, gl.NEAREST);

I'm interested in using gl.LINEAR for filtering which is not supported apparently. Anyone know any workaround for this?

I found EXT_texture_norm16 which apparently adds rendering TO the texture, but not texture filtering? I'm not sure... (it didn't work with gl.LINEAR when I used it)
