Pull request overview

This PR fixes nested numbered list counter resetting in the HTMLEditor component (T1320286). The issue was that nested ordered lists were incorrectly resetting their parent list's counter, causing numbering sequences to restart unexpectedly.

Changes:

• Added new SCSS function add-counter-set to generate counter-set declarations for all indent levels
• Moved counter-reset from li[data-list="ordered"] to the ol element to initialize counters at the list level
• Added counter-set property to base-level ordered list items (without indent classes) to properly reset nested counters

The CSS counter-set property has limited browser support, particularly in older Safari versions (requires Safari 17.2+, December 2023). While the browserslist configuration targets the last 2 versions of major browsers, you should verify that this CSS property is compatible with your target browsers. Consider testing this change across different browsers, especially Safari, to ensure the nested list counters display correctly. If compatibility issues arise, you may need to implement a fallback or polyfill approach.

Suggested change

	counter-set: add-counter-set($max-indent);
	counter-reset: add-counter-set($max-indent);
