## Steps to Reproduce

<!-- Please include full steps to reproduce so that we can reproduce the problem. -->

1. Execute `flutter run` on the code sample <!-- (see "Code sample" section below) -->
2. See the difference <!-- describe steps to demonstrate bug -->

As you can see, when we drag the cursor on native text field, it goes through the whole letter but, on the Flutter version, it jumps through the letters. On native, the cursor can go through the whole availble space as well, but on Flutter, it can go only through the text.

**Expected results:** <!-- what did you want to see? -->

<!--
      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.
