SVG rendering formatting issues with markdown input

[kurago-dev]

Description

When a node uses markdown formatting, some formatting issues appear.

From the live editor:

• Additional height is added to the node on the SVG output of the diagram when clicking "open SVG in new tab" (screenshot 1).
• Text is cut off (but height remains the same) on the SVG output of the diagram when clicking "download SVG" (screenshot 2).

For example, this diagram:

flowchart TD
    A("test")
    B("`test format`")

flowchart TD
    A("test")
    B("`test format`")

Steps to reproduce

1. Create a diagram with markdown format in one of the nodes
2. Render the diagram as SVG
   • Open SVG in new tab
   • Download SVG from editor
