Error on using link annotation with no selected value

[lcnogueira]

Describe the bug

When using a block type field, Sanity adds a "link" annotation to the studio by default. Sometimes using that annotation link throws an error.

To Reproduce

Steps to reproduce the behavior:

1. Go to any block type field.
2. Move the mouse cursor to the end of the line and press "space" to move away from the last word on that line.
3. Click the "Link" annotation.
4. See an error that looks like this:

Error: Cannot resolve a DOM point from Slate point: {"path":[28,0],"offset":20}

I also recorded a video in case it's helpful:

Expected behavior

It should either 1) disable the link annotation button or 2) select the last word on that line to apply the link.

Thank you for reporting this. There seems to be an off-by-one error going on here. I'll look into it.
