Describe the issue:

Sticky component loops forever if background-color is not set for page

Actual behavior:

This loop in _getBackground() never exits

while (window.getComputedStyle(curr).getPropertyValue('background-color') === 'rgba(0, 0, 0, 0)' ||
window.getComputedStyle(curr).getPropertyValue('background-color') === 'transparent') {
if (curr.parentElement) {
curr = curr.parentElement;
}
}

Expected behavior:

Should check for curr == html and return
