As shown in the case, use css transform scale to zoom，RenderWidth is not equal to ClientRect width. Causes problems in picking.
On the other hand, using the third parameter of setSize cannot force the setting of width and height
I answered here Css scale and scene picking - Questions - Babylon.js (babylonjs.com) seems like you found a fix for it, do you want to submit a fix?
Not yet. I need you to see the problem of setSize forcing the width and height to be invalid.
After setting, the width and height will be restored to the original value when the next frame is rendered
