Multiple legends are not independent in their placement and placement is not consistent

I am currently experimenting with the new-ish multi-legend feature. Unfortunately I seem to have stumbled across a case in which the legends are not behaving independently even though it is not clear why.

The following code demonstrates this:

from copy import deepcopy
import plotly.graph_objects as go

error_fig = {
    'data': [
        {
            'legend': 'legend2',
            'showlegend': True,
            'type': 'scatter',
            'x': [0, 1],
            'xaxis': 'x2',
            'y': [0, -1],
            'yaxis': 'y2'
        },
        {
            'legend': 'legend3',
            'showlegend': True,
            'type': 'scatter',
            'x': [0, 1],
            'xaxis': 'x3',
            'y': [0, 1],
            'yaxis': 'y3'
        },
        {
            'legend': 'legend3',
            'showlegend': True,
            'type': 'scatter',
            'x': [0, 1],
            'xaxis': 'x3',
            'y': [0, -1],
            'yaxis': 'y3'
        },
        {
            'legend': 'legend3',
            'showlegend': True,
            'type': 'scatter',
            'x': [0, 1],
            'xaxis': 'x3',
            'y': [0, 1],
            'yaxis': 'y3'
        },
        {
            'legend': 'legend3',
            'showlegend': True,
            'type': 'scatter',
            'x': [0, 1],
            'xaxis': 'x3',
            'y': [0, 1],
            'yaxis': 'y3'
        }
    ],
    'layout': {
        'legend2': {
            'orientation': 'v',
            'visible': True,
            'x': 0.515,
            'xanchor': 'left',
            'xref': 'paper',
            'y': 0.3,
            'yanchor': 'top',
            'yref': 'paper'
        },
        'legend3': {
            'entrywidth': 0.2,
            'entrywidthmode': 'fraction',
            'orientation': 'h',
            'visible': True,
            'x': 0.95,
            'xanchor': 'left',
            'xref': 'paper',
            'y': 1.0,
            'yanchor': 'top',
            'yref': 'paper'
        },
        'xaxis2': {'anchor': 'y2', 'domain': [0, 0.5]},
        'xaxis3': {'anchor': 'y3', 'domain': [0.45, 0.95]},
        'yaxis2': {'anchor': 'x2', 'domain': [0, 0.3]},
        'yaxis3': {'anchor': 'x3', 'domain': [0.7, 1.0]}
    }
}


correct_fig = deepcopy(error_fig)
correct_fig["layout"]["legend3"]["x"] = 1

fig_correct = go.Figure(correct_fig)
fig_correct.show()

fig_error = go.Figure(error_fig)
fig_error.show()

Where fig_correct produces this output upon png-download (The issue also exists in interactive mode with varying severity based on screen size):

fig_error produces this:

Which for me makes no sense as the only change that occurred was the placement of legend3 along x. I would therefore not expect legend2 to move. Additionally, for me it does not make any sense, why any large movement should occur at all, as I only changed the x-coordinate of legend3 by 0.05 .

For me the Issue only occurs when using "orientation": "h".

I am on Python 3.11.1
My pip dump:

Package    Version
---------- -------
packaging  23.1
pip        22.3.1
plotly     5.17.0
setuptools 65.5.0
tenacity   8.2.3

Commencez par exécuter la reproduction Python fournie avec Plotly 5.17.0 et comparez les mises en page de légendes multiples horizontales en mode interactif et dans la sortie PNG. Aucun fichier source ni test n’étant indiqué, suivez les points d’entrée du positionnement des légendes et du rendu de la mise en page à partir de la reproduction ; le travail est terminé lorsque le déplacement de legend3 ne déplace plus unexpectedly legend2 et ne provoque plus de déplacement disproportionné.
