different behavior for `.show()` and `.write_image()` with `ticksuffix`/`tickprefix`

I noticied two different behavior while using (ticksuffix or tickprefix) and tickvals parameter to update an axis when I want to display or save the graph.

Plotly version : 5.22.0

Reproduction code :

import plotly.graph_objects as go
fig = go.Figure(
    data=[go.Bar(x=[1,2], y=[2,3]),],
    layout=dict(xaxis=dict(tickvals=[1,2],tickprefix='a', ticksuffix='b'))
)
fig.show()
fig.write_image(f"graphs/test.png", format="png")

.show() output :

.write_image() output :

Start with the reproduction code in the issue and compare the output from fig.show() with fig.write_image(..., format="png") when tickvals, tickprefix, and ticksuffix are set. Trace the two rendering paths to identify why the axis labels differ; done means both outputs apply the prefix and suffix consistently, with a regression test for the reported case.
