MWPW-182328 modal hash

[zagi25]

Issue: If window.location.hash is changed manually, modal stays open resulting in possibility to open another modal on top of already open modal or scrolling the page to the heading while modal is open

• Close modal when hash changes
• Prevent focusing modal button if new hash is heading hash
