fix: incorrect cursor movement behaviour

[Jei-sKappa]

fixes #745
Previously the moveVertical function only moved the cursor 'node to node' without taking into consideration multiline nodes or some portion of a line with different fontSize (ex: a paragraph with size 16 but with a bolded word with size 32). This was caused by the PR #657 that closes #656 and #589.

@Jei-sKappa Thanks for contributing. Please format the code.

@LucasXu0 Thanks for your reply! Based on the response of GitHub Action it seems like the problem is in the commit message and not in the code. Am I right?

Except for the commit message, you need to format the Dart code too. Please click on the CI and check the error.

@LucasXu0 Sorry for the late response.
I just pushed a new update to the pull requests that should fix the test's errors in the CI.
Unfortunately my first commit text exceeds the length defined in commitlint and the CI keeps failing 'cause of this.
Can I ignore it? If not what should I do to fix this?

You don't have to worry about the commitlint failing, it's not important 👍

We need to introduce some more tests so we can stop a regression from occurring.

We can add tests in a new PR, I will open a new issue once @LucasXu0 has taken a look at this PR.
