FigureWidget + go.Image.source breaks notebook kernel in VSCode

I encounter a bug in VSCode notebook when using a FigureWidget for a go.Image trace using source string instead of z attribute (px.imshow optimization).

The bug is: once you hover the image with mouse the kernel is unresponsive, i.e. you can't run any cell anymore.

The bug is not present when running the notebook through Jupyter web interface.

Reproducible example

import numpy as np
import plotly.express as px
import plotly.graph_objects as go
from plotly.utils import image_array_to_data_uri

img = (np.random.rand(10, 10, 3) * 255).astype(np.uint8)
img_str = image_array_to_data_uri(img)

# --- Using normal go.Figure is OK
# px.imshow(img) # OK
# go.Figure(go.Image(z=img)) # OK
# go.Figure(go.Image(source=img_str)) # OK

# --- Using go.FigureWidget and Image.z is OK
# go.FigureWidget(go.Image(z=img)) # OK

# --- Using go.FigureWidget and Image.source is NOT OK
# go.FigureWidget(px.imshow(img)) # NOK
go.FigureWidget(go.Image(source=img_str)) # NOK

在 VSCode notebook 中复现所提供的 FigureWidget 示例，对比 go.Image(source=...) 与 go.Image(z=...) 以及等效的 Jupyter Web 运行。跟踪悬停在基于 source 的图像上所触发的 FigureWidget notebook 交互；当悬停不再导致 kernel 无响应且单元格能够继续正常执行时，该 issue 即完成。
