silverbullet Uncaught RangeError: Position 779 is out of range for changeset of length 778

I was adding an object to a page and suddenly i couldn't move my cursor anymore. I was in vim mode when this happened and the red highlighting wouldn't move but the edits would happen where they were supposed to. Switching vim mode off, I saw the same thing: cursor does not move but pressing the arrow keys and typing something would as expected.

When trying to edit the page nothing will save.

There's an error spammed in console, here's the full log:

I uploaded the markdown file as it was when the error happened here

Manually changing the file to have an extra character at the end fixed the issue

I see 3 suspicious things. This is how the file in fact ends:

```#drive
name: "Sandisk”

the code block is not ended
the second quotation mark of the "Sandisk” is not an ASCII quotation mark but U+201D Right Double Quotation Mark Unicode Character
the last EOL is missing

thank you for pointing to the potential causes.

i just ran into the same issue and was able to verify these conditions:

i started a code block ```yaml
i entered 2 lines into it (not pressing enter on the end of the second line)
i used up-arrow key to get out of the block
the whole application became unusable (while on that specific page)

so i went to test what is really causing this.

in my case the quotation marks did not make a difference. tried both, and even not closed. did not cause an issue for me.

but "code block is not ended" causes an issue for me IF there is no newline at the last line. although it works if not ended BUT the last line has a newline

also: ending the code block (with 3 backticks) BUT still having no newline after that, also works.

i fixed my file outside of silverbullet, but silverbullet itself was used to get the file into an invalid state (see the 4 steps above).

hopefully this helps in pinpointing the underlying code issue / edge case
