fig.update_layout(xaxis_type="category") breaks make_subplots(shared_xaxes=True)

This one is pretty simple to explain and see. Create a subplot with two or more plots that are using the same x-axis data, enable shared_xaxes=True, plot it, and it works as intended; zooming in on one plot zooms in on both plots.

When updating the layout to xaxis_type="category", for categorical data, even when both both subplots have the same x-axis data and shared_xaxes=True is set to true, it no longer works; the axis are no longer shared. Zooming in on one plot no longer effects the other plot.

Tested on: plotly 5.24.1, python 3.13

首先，使用 make_subplots(shared_xaxes=True)、分类 x 轴数据和 xaxis_type="category" 重现报告的 subplot 情况。比较 layout 更新前后的缩放行为；当 x 轴数据共享时，缩放一个 subplot 也会缩放另一个 subplot，即表示完成。
