Issue with elk layout : rendered correctly in live editor but tricky to export

[Sulray]

Describe the bug
ELK layout is correctly rendered in Mermaid Live Editor but not in different kind of exports:

• The copy to clipboard
• The PNG in a new tab
• The SVG in a new tab
• The Kroki in a new tab

For an unknwown reason, the only exports that seems to work are the PNG (that is not transparent so a bit useless) and the SVG downloads

To Reproduce
Link to Live Editor:

Steps to reproduce the behavior:

1. Go to 'Actions'
2. Click on "Copy image to clipboard" or button to open PNG/SVG/Kroki in another tab
3. See that the result do not use elk layout as rendered in Mermaid Live Editor

Expected behavior
Result with elk layout.

Additional context
Another thing which is weird is that when I click on my Mermaid Live Editor link, I have to reload one time the page to see the output.
