Transparent markers misbehaving in plotly.express.scatter

Description

I create a scatter plot and use the color and size arguments. One subset gets transparent markers and is not visible in the plot and the legend.

But: if I hover over an area, where a marker should be, the tool tip is appearing, see figure below:

Expected Behavior

Marker should be visible in plot and legend.

Reproduction

Running the code below I get the figure above.

# %%
# Imports

import sys

df.set_index('id', inplace=True)

df.x = df.x.astype('float32')
df.y = df.y.astype('float32')
df.loop_number = df.loop_number.astype('category')  # As category to use color labels, not a color bar.
df.repetition = df.repetition.astype('int32')

df.head()

# %%
# Create Scatter Plot

px.scatter(
  df,
  x='x',
  y='y',
  color='loop_number',
  size='repetition',
  labels={
    'color': 'Type',
    'size': 'Size'
  },
  hover_name=df.index
)

Ejecuta la reproducción de Python proporcionada mediante plotly.express.scatter con color='loop_number' y size='repetition'. Inspecciona por qué el subconjunto transparente se omite tanto del gráfico como de la leyenda, a pesar de que sigue siendo accesible mediante hover; se considera terminado cuando los marcadores y la entrada de la leyenda de ese subconjunto sean visibles, preservando el comportamiento de scatter informado.
