First, let me say thanks for your work on HappyDOM, I'm really happy with the performance. I'm using it to feed Mozilla's Readability library to extract articles from HTML documents.

Steps to Reproduce

document.body.innerHTML = '<div>The <strong>quick</strong> brown fox</div><div>Jumped over the lazy dog</div>'
document.body.innerText

Returns
The quick brown foxJumped over the lazy dog

Expected (Firefox and Chrome)
The quick brown fox\nJumped over the lazy dog

I verified this behavior in Chrome and Firefox. As far as I can tell, they do it for block level elements.

This is causing things like <li> lists to get merged together. My temporary fix is to append a whitespace to every text, but this still creates runon sentences with no break.

Another inconsistency is how newlines within the HTML are handled:

document.body.innerHTML = '<span>The quick brown fox</span>\n<span>Jumped over the lazy dog</span>'
document.body.innerText

Returns
The quick brown fox\nJumped over the lazy dog

Expected
The quick brown fox Jumped over the lazy dog

Logically, the \n is treated as whitespace and not specifically a newline (i.e. word-wrapped code doesn't mean it should be rendered with the same breaks)

Checking in on this. I just confirmed this is still happening on v3.1.1. It turns out that my workaround is causing some unintended behavior. Maybe my use-case is not very common so no one else has noticed this issue.

Hi @devinellis! 🙂

Thanks for reporting!

I am not able to reproduce this bug. I have compared Happy DOM with Firefox and I get the same result between them. Am I missing something? 😅

Feel free to close. I have switched to using linkedom for my use-case.

Too bad to hear that Happy DOM couldn't help you with your case.

I believe I understand the problem now. I assumed that "innerText" for <body> behaves the same as "innerText" for other elements, but it seems like they behave differently. I tested with a <div> element.

 var div = document.createElement('div');
 
 div.innerHTML = '<div>The <strong>quick</strong> brown fox</div><div>Jumped over the lazy dog</div>';
 document.body.innerHTML =  '<div>The <strong>quick</strong> brown fox</div><div>Jumped over the lazy dog</div>';
 
 // Outputs: "The quick brown fox\nJumped over the lazy dog"
 console.log(document.body.innerText);
 
 // Outputs: "The quick brown foxJumped over the lazy dog"
 console.log(div.innerText);

Actually, it is not the <body> element that behaves different. It should just render it differently if it is connected to the document or not.
