multiline text incorrectly calculates intrinsic height

[matthew-carroll]

Multiline text on web appears to compute the wrong intrinsic height. Here is a repo of the problem occurring:

Run the Dart Pad and press the button at the bottom of the screen. You'll see an overflow that shouldn't happen.

Here is the same Dart Pad with only a single line of text and the overflow does not occur:

This bug seems to still exist even with the FLUTTER_WEB_USE_EXPERIMENTAL_CANVAS_TEXT flag.

This issue only happens when the window exceeds a certain width. If I shrink the window size in your repro DartPad, the overflow goes away:

Here's what it looks like when I increase the width after a certain point:

I was able to repro this on native iOS when I use landscape mode to get the necessary width:

This is most likely a duplicate of #48679. The way RenderParagraph calculates its intrinsics is buggy.

@goderbauer can you please confirm that this can be closed in favour of the one you mentioned?
