Italic formatting is lost when typing after applying italic

Phenomenon

When applying italic formatting to selected text and then continuing to type, the italic formatting is not maintained for the newly typed characters in Edge on Windows.

Reproduction example

1. Create a contenteditable div.
2. Type some text.
3. Select the text and apply italic formatting (Ctrl+I or through execCommand).
4. Place the caret at the end of the italic text.
5. Continue typing.

Observed behavior

• In Edge on Windows, newly typed characters after the italic text are not italic.
• The formatting state appears to be lost when the caret moves.

Expected behavior

• Newly typed characters should inherit the formatting of the preceding text when the caret is within or immediately after formatted text.
