Converting a Legacy Editor page breaks anchor links in current editor

Issue Summary

Whenever we convert a page from the Legacy Editor to the current one, in case this page has anchor links, the links will break.

Steps to Reproduce

1. Create a new page using the Legacy Editor template, in case your site has it;
2. Generate some Lorem Ipsum text in your page;
3. At the bottom of the page, add an Anchor macro named Anchor1;
4. Go to the top of the page, highlight a piece of text and hit CTRL + K/Command + K to insert a link;
5. Go to the Advanced option;
6. In the Link field, insert #Anchor1 (which is the name of the anchor we added);
7. Upon publishing the page, click over the Anchor link - notice you are redirected to the bottom of the page;
8. Edit the page;
9. Convert it to the current editor;
10. Upon publishing the page, click over the anchor link.

Expected Results

You land to the bottom of the page, as the anchor is there.

Actual Results

Nothing happens.

Notes:

• The issue occurs because after we convert the page, the anchor links get changed to #PageTitle-AnchorName.

Workaround

There is nothing we can do to avoid this behavior, so upon you convert your page, make sure to manually fix the anchor links to the concerned anchors.
