Summary of Changes

Smart Search parses HTML content among other things by stripping the tags from it and then splitting it at the whitespace. Unfortunately if you have content which has no whitespace without the HTML tags, Smart Search will fail to index that content entirely. In my specific case, my articles contain tables of product numbers, which are generated by a plugin and thus don't contain any whitespace. This PR extends the list of elements to "space out" a bit before stripping the tags, so that Smart Search will be able to still index this.

Testing Instructions

1. Switch to no editor in your site for this test. TinyMCE for example will automatically format the below code, thus inserting spaces.
2. Create an article and paste the following as content: <table><tr><td>Test</td><td>String</td><td>String</td><td>String</td><td>String</td><td>String</td><td>String</td><td>String</td><td>String</td><td>String</td><td>String</td></table>
3. Save the article
4. Search for String in the frontend.
5. Apply patch
6. Clear index and start indexing again (The bug is during indexing, so you can't just apply the patch and search again directly.)
