[BUG]: Subplot LaTeX titles misaligned

Description

make_subplots produces plots with misaligned LaTeX titles:

Nor do they seem to be properly centered.
Saving the image with fig.write_image(img.png) does not render it differently.

If you remove the letter "p" from the title on the right or add one on the left, that seems to "solve" the vertical alignment problem.

Steps to reproduce

from plotly.subplots import make_subplots

fig = make_subplots(rows=1, cols=2,
                    subplot_titles=(r'$\Large\text{Investment Rate}$',r"$\Large\text{Experts' Capital Share}$"))

fig.add_scatter(x=[], y=[], row=1, col=1)
fig.add_scatter(x=[], y=[], row=1, col=2)

fig.update_layout(#template="plotly_white+presentation", 
                  height=600, width=1200)
fig

Version: 6.8.0

I also think the default positioning of the title should be a tiny bit higher.

使用 plotly 6.8.0 运行提供的 Python 复现代码，从 make_subplots 和子图标题定位路径开始。将交互式渲染与 fig.write_image(img.png) 进行比较；当 LaTeX 标题垂直对齐且居中，并且在包含该请求的情况下默认标题位置略高时，即表示完成。
