onnxruntime-web bug, who can solve this problem, dear friends

Dear friends, Who can solve this problem?
self.b1, self.b2, self.b3, self.b4 are sublayers of mobilenetv3.
(1)slow when return f1,f2,f3,f4
def forward(self, x):
f1 = self.b1(x)
f2 = self.b2(f1)
f3 = self.b3(f2)
f4 = self.b4(f3)
return f1,f2,f3,f4
when I return f1,f2,f3,f4 ， the onnx used in chrome is very slow. (ort.min.js using wasm or webgl)

(2) fast when return f4
def forward(self, x):
f1 = self.b1(x)
f2 = self.b2(f1)
f3 = self.b3(f2)
f4 = self.b4(f3)
return f4
when I only return f4 ， the onnx used in chrome is very fast. (ort.min.js using wasm or webgl)
but in normal , the two way should be the same time
