Opacity and color not working together in px.scatter

I am creating a plot, which has color and opacity together. When I use color, the opacity doesn't work correctly. Here is a reproducible example:

a = [0.067, 2.159, 0.253, 4.72, 0.614, 4.929, 5.647, 1.624, 0.946, 5.408, 0.308, 0.765, 0.006, 0.326, 4.201, 5.976, 1.644, 4.7, 5.67, 5.002, 5.208, 5.658, 6.821, 6.081, 2.687, 3.106, 0.207, 6.139, 0.242, 4.214, 3.975, 4.639, 5.744, 1.725, 5.753, 7.863, 1.67, 4.466, 5.283, 4.683, 0.764, 5.408, 5.279, 1.088, 0.874, 4.72, 5.39, 0.514, 0.023, 0.196, 2.781, 5.317, 5.262, 4.576, 4.683, 6.437, 6.614, 2.27, 2.92, 2.812, 6.383, 0.486, 6.082, 0.791, 0.283, 0.047, 4.671, 3.362, 0.314, 3.294, 0.134, 3.662, 6.025, 7.097, 2.089, 0.019, 1.058, 6.095, 2.436, 0.563, 5.096, 6.824, 1.707, 1.621, 6.058, 5.621, 0.956, 2.673, 5.751, 3.286, 0.809, 4.468, 6.026, 0.089, 0.29, 5.556, 4.81, 4.811, 5.08, 4.671, 4.614, 6.417, 4.9, 3.398, 6.091, 6.511, 6.46, 5.596, 6.4, 7.219, 5.474, 5.541, 5.542, 5.014, 1.853, 2.726, 4.681, 0.985, 0.114, 0.171, 4.494, 3.783, 0.501, 4.531, 4.424, 5.573, 5.757, 4.991, 5.715, 5.54, 5.127, 4.327, 5.125, 5.545, 4.397, 5.174, 2.417, 2.209, 4.774, 0.095, 0.577, 1.149, 5.158, 1.338, 3.482, 5.143, 0.849, 0.214, 0.113, 3.696, 4.432, 4.29, 4.507, 5.24, 4.158, 4.494, 0.0, 0.851, 5.578, 1.604, 4.856, 4.424, 2.316, 0.259, 1.39, 3.12, 0.446, 1.017, 2.179, 0.017, 3.438, 3.665, 0.538, 1.732, 5.781, 0.241, 0.21, 4.779, 4.519, 0.507, 0.295, 0.956, 5.641, 5.118, 0.9, 4.499, 5.07, 2.568, 1.089, 6.174, 4.45, 0.863, 1.943, 3.451, 3.276, 0.026, 1.378]
b = [int(bool(i<=2)) for i in a]
c = ['r', 'r', 'r', 'r', 'r', 'b', 'b', 'r', 'r', 'r', 'r', 'b', 'r', 'r', 'b', 'r', 'b', 'b', 'b', 'b', 'r', 'b', 'r', 'r', 'r', 'r', 'r', 'r', 'r', 'r', 'b', 'r', 'r', 'b', 'r', 'r', 'r', 'b', 'b', 'r', 'r', 'b', 'r', 'r', 'b', 'b', 'r', 'r', 'r', 'r', 'b', 'b', 'b', 'r', 'r', 'b', 'r', 'r', 'b', 'r', 'r', 'b', 'r', 'b', 'r', 'r', 'r', 'b', 'b', 'r', 'r', 'r', 'r', 'r', 'r', 'b', 'b', 'b', 'r', 'r', 'b', 'b', 'r', 'b', 'b', 'r', 'r', 'b', 'r', 'r', 'r', 'r', 'r', 'r', 'b', 'r', 'b', 'b', 'b', 'r', 'r', 'r', 'r', 'r', 'r', 'b', 'b', 'b', 'b', 'b', 'b', 'r', 'b', 'r', 'r', 'b', 'r', 'r', 'b', 'b', 'r', 'r', 'r', 'b', 'b', 'r', 'r', 'b', 'b', 'b', 'r', 'r', 'r', 'r', 'r', 'b', 'r', 'r', 'r', 'r', 'r', 'b', 'r', 'r', 'r', 'r', 'b', 'r', 'r', 'r', 'r', 'b', 'b', 'r', 'r', 'r', 'r', 'r', 'b', 'b', 'r', 'r', 'r', 'r', 'b', 'b', 'b', 'b', 'b', 'r', 'b', 'b', 'b', 'r', 'r', 'r', 'r', 'b', 'r', 'r', 'r', 'b', 'r', 'r', 'b', 'b', 'b', 'r', 'r', 'b', 'r', 'b', 'b', 'r', 'r', 'r', 'b']

when I use:

fig = px.scatter(y=a,opacity=b,text=['x']*197) 
fig.show()

I get this image, which is correct (anything below 2 has an opacity of 1)

but when I use both color and opacity, it gets messed up:

fig = px.scatter(y=a,opacity=b,color=c,text=['x']*197) 
fig.show()

從 issue 中的 px.scatter 範例開始，執行兩個版本：先單獨使用 opacity，接著將 opacity 與 color 結合使用。比較產生的繪圖對小於 2 的點的行為，並驗證加入 color 不會改變所提供的 opacity 值。當可重現範例能正確渲染 color 和 opacity 時，即表示完成。
