## Steps to Reproduce

<!-- Please include full steps to reproduce so that we can reproduce the problem. -->

1. Execute `flutter run example` on the code sample <!-- (see "Code sample" section below) -->
2. Copy some text with more than one line to the clipboard
3. Try pasting any input in Flutter

**Expected results:** <!-- what did you want to see? -->
That the text kept the line breaks

**Actual results:** <!-- what did you see? -->
On the web, pasted text loses line breaks, even when the input has maxLines greater than 1

<!--
      Please create a minimal reproducible sample that shows the problem
      and attach it below between the lines with the backticks.

      To create it you can use `flutter create bug` command and update the `main.dart` file.

      Alternatively, you can use https://dartpad.dev/
      which is capable of creating and running small Flutter apps.

      Without this we will unlikely be able to progress on the issue, and because of that
      we regretfully will have to close it.
