Cannot place caret outside of inline code

Write the following text:

> This is `inline code`.

Backspace to delete the `.` at the end of the line and the caret jumps into the inline code tag. You now cannot add normal text at the end of this line. Most editors which work in a similar way allow you to click outside of the inline code or use the arrow keys to place the caret outside.

Start by reproducing the caret jump in the Editor.js inline-code tool using the steps in the issue, then inspect the tool's caret and inline-code handling. Done means deleting the trailing period no longer traps the caret inside the inline code, and clicking or using arrow keys can place it after the code.
