feat: respect single empty line

[bram209]

resolves #27

Btw: This makes it so it does not respect no newlines when the closing tag is on a line by itself @bram209 :

            <div>
                <div
                    class="foo"
                    class="foo"
                    class="foo"
                    class="foo"
                    class="foo"
                    class="foo"
                    class="foo"
                >
                    <i class="bi-google"></i>
                    "Sign in with google"
                </div>
            </div>

formats to

            <div>
                <div
                    class="foo"
                    class="foo"
                    class="foo"
                    class="foo"
                    class="foo"
                    class="foo"
                    class="foo"
                >
+                                                                                                                                                                                                                                   
                    <i class="bi-google"></i>
                    "Sign in with google"
                </div>
            </div>

I am trying to look into this as well, but can't figure out how to fix the issue yet

[bram209]

ah check, I think I know the issue, sorry for the inconvenience

[seblj]

No problem at all! Thanks for looking into it :)

[bram209]

Should be fixed now @seblj

[seblj]

Works perfectly! Thank you!
