Twig removes spaces before variables in php 7.4

If it is not possible to update the version of the Twig library, but the server only has PHP 7.4 and higher, then there is a quick fix for the problem with the disappearance of spaces before variables.

Available:

<span>Brand name {{global.brand}}</span>

Output without space

<span>Brand nameAriston</span>

Solution:

/twig/twig/lib/Twig/Lexer.php

$text = $textContent = substr($this->code, $this->cursor, $position[1] - $this->cursor);
if (isset($this->positions[2][$this->position][0])) {
    $text = rtrim($text);
}

replace with

$text = $textContent = substr($this->code, $this->cursor, $position[1] - $this->cursor);
if (isset($this->positions[2][$this->position][0]) && ($this->options['whitespace_trim'] === $this->positions[2][$this->position][0])) {
    $text = rtrim($text);
}
