Mermaid diagram size in pptx

[shriv]

Bug description

I've had to update to the latest release of Quarto to get Mermaid diagrams rendering within pptx. However, it seems like the sizing feature doesn't work.

Steps to reproduce

• Install Quarto 1.5.57. I did this via nix. Install chromium if needed quarto install chromium.
• Put the following in test.qmd and run quarto render test.qmd.
• Change values of fig-height or fig-width. The mermaid diagram doesn't change size.
