Property Grid: Stepping through adjacent filtered matches doesn't work

[grigasp]

Repro:

1. open presentation-test-app
2. open the default sample imodel, use Items ruleset
3. in the tree view filter, enter "e"
4. step through filter matches until two adjacent "e" are found
5. try to step through them - notice that they're handled as one match

The issue is in third-party library: react-highlight-words, described here: https://github.com/bvaughn/react-highlight-words/pull/82.

Looks like it's not going to be fixed. Need to consider forking and fixing ourselves or looking for another library.
