340-357: Performance improvement opportunity in list container detectionThe newly added logic to detect list containers is a good improvement for better element targeting, but there's an inefficiency in the implementation. The
findDeepestElement(elements)function is called in each iteration of the loop, recalculating the same result multiple times.Consider computing the deepest element once before the loop to improve performance:
// Logic to get list container element let targetElement = null; +const deepestEl = findDeepestElement(elements); for (const element of elements) { - const deepestEl = findDeepestElement(elements); if (deepestEl && element !== deepestEl) { if (element.contains(deepestEl) && element !== deepestEl.parentElement && element.tagName !== 'HTML' && element.tagName !== 'BODY') { targetElement = element; break; } } } let deepestElement = targetElement || findDeepestElement(elements);

874-891: Duplicate inefficient code patternThe same inefficient pattern is repeated here, where
findDeepestElement(elements)is called in each loop iteration.Apply the same optimization suggested for the previous occurrence to move the calculation outside the loop.

🛠️ Refactor suggestion
Same inefficiency in the third occurrence
This is the third instance of the same inefficient pattern where findDeepestElement(elements) is repeatedly called inside the loop.
Since this pattern is repeated in three places, consider creating a helper function that implements this list container detection logic efficiently, which can then be reused in all three locations:
function findTargetElementOrDeepest(elements) {
const deepestEl = findDeepestElement(elements);
if (!deepestEl) return null;
let targetElement = null;
for (const element of elements) {
if (element !== deepestEl &&
element.contains(deepestEl) &&
element !== deepestEl.parentElement &&
element.tagName !== 'HTML' &&
element.tagName !== 'BODY') {
targetElement = element;
break;
}
}
return targetElement || deepestEl;
}This would improve both performance and maintainability by eliminating duplicated code.
