If the caret is positioned within the JS editor, then you change to another tab or another app and subsequently return to the jsfiddle tab, the caret moves to the top of the JS box. Highlighting is also lost.
Expected behavior: the caret should remain in the place where it was left when the tab lost focus. Highlighted text should remain as it was before losing focus.
Test environment:
Windows/Firefox 145.0.2
