-= Rich Text Manipulation
-
-When we sanitize rich text, we have to update the entity indices as the
-text is modified. This can be modeled as inserts() and deletes() of the
-rich text string. The possible scenarios are outlined below, along with
-their expected behaviors.
-
-NOTE: Slices are start inclusive, end exclusive
-
-== richTextInsert()
-
-Target string:
-
-   0 1 2 3 4 5 6 7 8 910   // string indices
-   h e l l o   w o r l d   // string value
-       ^-------^           // target slice {start: 2, end: 7}
-
-Scenarios:
-
-A: ^                       // insert "test" at 0
-B:        ^                // insert "test" at 4
-C:                 ^       // insert "test" at 8
-
-A = before           -> move both by num added
-B = inner            -> move end by num added
-C = after            -> noop
-
-Results:
-
-A: 0 1 2 3 4 5 6 7 8 910   // string indices
-   t e s t h e l l o   w   // string value
-               ^-------^   // target slice {start: 6, end: 11}
-
-B: 0 1 2 3 4 5 6 7 8 910   // string indices
-   h e l l t e s t o   w   // string value
-       ^---------------^   // target slice {start: 2, end: 11}
-
-C: 0 1 2 3 4 5 6 7 8 910   // string indices
-   h e l l o   w o t e s   // string value
-       ^-------^           // target slice {start: 2, end: 7}

-Target string:

-   0 1 2 3 4 5 6 7 8 910   // string indices

-Scenarios:
-
-A: ^---------------^       // remove slice {start: 0, end: 9}
-B:               ^-----^   // remove slice {start: 7, end: 11}
-C:         ^-----------^   // remove slice {start: 4, end: 11}
-D:       ^-^               // remove slice {start: 3, end: 5}
-E:   ^-----^               // remove slice {start: 1, end: 5}
-F: ^-^                     // remove slice {start: 0, end: 2}
-
-A = entirely outer   -> delete slice
-B = entirely after   -> noop
-C = partially after  -> move end to remove-start
-D = entirely inner   -> move end by num removed
-E = partially before -> move start to remove-start index, move end by num removed
-F = entirely before  -> move both by num removed
