Fix the issue where applying a highlight in the Squarespace editor causes the page to scroll to the top and lose focus.

🐞 Current behavior

• When a user selects text and applies a highlight, the editor scrolls to the top.

• The user loses focus on the edited content.

• This disrupts editing flow, especially on long pages.

✅ Expected behavior

• After applying a highlight:

• Scroll position remains unchanged.

• Focus stays on the edited text.

• No unnecessary re-render of the editor.

🔧 Technical notes

• Likely caused by a full re-render or a forced window.scrollTo(0, 0) call.

• Or prevent the editor from reloading the entire DOM when applying inline styles.

🧩 Acceptance criteria

• No scroll-to-top after applying highlight.

• Cursor remains in place for continued editing.

• Works across all text block types.

• No regressions on other styling actions (bold, italic, etc.).
