## Steps to Reproduce

1. Execute `flutter run` on the code sample <!-- (see "Code sample" section below) -->
2. Turn on VoiceOver. (Only VoiceOver, No problem with Talkback)
3. Focus to Item.
4. Double tap + Long press to reorder item. 
5. Releasing the finger moves the focus to an incorrect position.

**Expected results:** Focus should be on Item.

**Actual results:** Step 5 will move the focus to the incorrect position and tapping on the Item will no longer focus it. (See attached video, the focus has shifted to the upper-left. It will be easier to understand if you turn off the mute.)

<!--
      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.
