Mermaid editor: Changes to Mermaid diagram lost when scrolling

[benjaoming]

I had worked on new contents in a Mermaid diagram for about one hour.

All the changes were rendering in the diagram preview. I scrolled up the page to copy a few things from another diagram and scrolled back down. The diagram that I had been editing had now reverted and all my changes were gone.

I don't know how to explain any more of this.

I'm editing a page with a bunch of different diagrams and a lot of text.

Questions

• Any related bugs to look into?
• Is the GitBook editor known to be buggy in Firefox?

Other info

• I use Firefox, the best browser in the world, I'm not gonna change that.
• My network connection worked fine.
• My user session didn't seem to have expired.
• The scrolled view and cursor position in general seems to get confused when I'm scrolling.
• Another weird bug: I can't insert links, when I mark some text and insert the link, the cursor jumps to the beginning of the page and forgets the text that I was marking, so the https:/... URL text is inserted at the beginning of the page.
