From a quick look at the code, no. The construction is basically:
QTextBlock block = control->document()->findBlock(position);
if (!block.isValid())
return;
[...]
QTextLine line = block.layout()->lineForTextPosition(position -
block.position());
lineForTextPosition() can only return invalid if the position passed is not in
the block in question. But findBlock() returned this block for that position,
so that position should be in this block.
That means the problem is elsewhere. There's something else at work here.

You have to test. The code above is pasted from Qt 5.11, but since the problem
is unlikely to be in this piece of code, I can't tell from looking at the code
if the problem is still there.
