Steps to reproduce
Create a transition-group with nested elements
Condense template removing \r \n keeping only spaces between tags
What is expected?
This should work without warnings
What is actually happening?
It gets the error:
Cannot read properties of null (reading 'getBoundingClientRect')
The cause of the reported error come from this section of parseChildren function:
if (!prev ||
!next ||
(shouldCondense &&
(prev.type === 3 /* COMMENT */ ||
next.type === 3 /* COMMENT */ ||
(prev.type === 1 /* ELEMENT */ &&
next.type === 1 /* ELEMENT */ &&
/[\r\n]/.test(node.content))))) {
removedWhitespace = true;
nodes[i] = null;
}
else {
// Otherwise, the whitespace is condensed into a single space
node.content = ' ';
}
The problem is, if section has only spaces without \r or \n, it doesn't get removed but replaced with a space.
This make render a text section inside a transition-group between animated elements, which cannot be animated.
