Canvas collapse when init with a display-none wrapper

[Huxpro]

just change some code in the sample/bar.html

<div style="display: none;">
    <canvas id="canvas" height="450" width="600"></canvas>
</div>

the canvas will be set to height="0" and never back. (set back to display: block later)
even if I drag window to trigger re-calculate, the width response but height still 0.
