D9054 did multiple consecutive `immBegin()`/`immEnd()` draw calls to draw multiple lines at varying thickness. This would only work for the first line, then they'd all get a 1px thickness (at least on macOS). Issue was that `wide_line_workaround_end()` called `immBindShader()` directly to restore the old shader (which the workaround overrides). However this doesn't set `imm->builtin_shader_bound` which has to be done for the workaround to work on the next `immBegin()` call. Instead `immBindBuiltinProgram()` can be called.
