Summary

Not always does the Table of Context excludes correctly the 'exclude regex' from the search. For example, the regex '^(?![\s\t\w]*$).+}', which should eliminate titles only with spaces, tabs, etc. useful to remove unnecessary titles, works in 'preview' view, but not after we save the page.

Steps to Reproduce

1. Create 4 sections in a page
2. Add in 3 'h1' headings with text, and h2 in another
3. Add a ToC in the other section and add an 'almost empty' h1 heading (with only a space in the title) in this section
   • Make sure to select the space and see if it's heading 1
4. Add remove regex: '^(?![\s\t\w]*$).+'
5. Check if the empty header is included in ToC

Expected Results

It does not include the heading with a single space in preview mode or after saving the page.

Actual Results

It's excluded from the preview mode, but not when we save the page.

Workaround

None so far.
