The "spaceless" filter does not completely remove whitespace, may unnecessarily remove the following newline.

[Hajime-Sasaki]

Version: 3.1.4

Bug Description

The spaceless filter (also split) does not completely remove whitespace characters, may unnecessarily remove the newline character immediately following the block.

Steps To Reproduce

I couldn't save on https://fiddle.nette.org/latte by 500 error. Therefore, I wrote the code here;

Main template

Case 1.
{block |spaceless}
<ul>
    <li>Hello</li>
</ul>
{/block}
World.

---
Case 2.
<section>
{block |spaceless}
<ul>
    <li>Hello</li>
</ul>{/block}
World.
</section>

---
Case 3.
<section>
{block |spaceless}
  <ul>
    <li>Hello</li>
  </ul>{/block}
World.
</section>

Output

Case 1.
<section>
<ul> <li>Hello</li> </ul>World.
</section>

---
Case 2.
<section>
<ul> <li>Hello</li> </ul>
World.
</section>

---
Case 3.
<section>
<ul> <li>Hello</li> </ul>World.
</section>

Expected Behavior

I expected the following results for all;

<section>
<ul><li>Hello</li></ul>
World.
</section>

Remove internal whitespace, but do not remove the newline character immediately following the block.
