Fixes #1981

💡 Background and solution

Background:

1. element inner html string is copied, rather than a human-readable text.
2. the copy feature doesn't work for old browsers(such as IE)

Solution:

1. copy text rather than html. try to copy the element content as rich-text at first. if failed, copy the element innerText instead.
2. click event doesn't work on <svg> element for ie. add "pointer-events:none" css attribute to the svg element to trigger the click event of the parent <a> element. this also fix OnClick event for Icon component.
