Samples break in JS

[zhylmzr]

1. Remove old heaps version using haxelib.
2. Clone the master 1936c9c to haxe libs directory and rename 1,10,0.
3. Copy samples directory to ~/samples.
4. In ~/samples, run haxe gen.hxml && cd build/base2D && haxe base2D_js.hxml.
5. Open the index.html, the page is blank with many webgl warning:
   [.WebGL-0x138004bdc00] GL_INVALID_OPERATION: Vertex buffer is not big enough for the draw call

The version of hashlink work fine.

Other info:

1. macOS 13.4.1 (M1)
2. haxe version: 5.0.0-alpha.1+3a5140e

The compile outputs:
base2D.zip
