gl.texImage2D "Invalid argument" in IE 11

[jfirebaugh]

Many examples started failing in IE 11 after #7171 with an "Invalid argument" error here:

mapbox-gl-js/src/render/texture.js

Line 73 in 93fef1a

gl.texImage2D(gl.TEXTURE_2D, 0, this.format, width, height, 0, this.format, gl.UNSIGNED_BYTE, image.data);

Guessing here, but maybe IE 11 does not like 0 for width and height, which didn't happen before #7171 but now it is?

It's a good hypothesis, although I'm not sure how exactly that happens — does IE11 provide a stack trace?

Stack trace has mangled names, but the line numbers look accurate to unminified source:

ms.prototype.update [Line: 73, Col: 17], texture.js
ms [Line: 49, Col: 5], texture.js
eu.prototype.upload [Line: 252, Col: 13], tile.js
i.prototype.prepare [Line: 171, Col: 30], source_cache.js
Zi.prototype.render [Line: 299, Col: 13], painter.js
o.prototype._render [Line: 1642, Col: 9], map.js
Anonymous function [Line: 1683, Col: 17], map.js
