        <pre>When the start of a line contains a 2-consonant cluster that uses a *visible* virama, ::first-letter should highlight only the first consonant+virama. This corresponds to a grapheme cluster, as defined by Unicode.

Tests & results:
Interactive test, When ::first-letter is applied to Devanagari the browser will NOT select a 2-consonant cluster as a unit if the virama is visible

Interactive test, When ::first-letter is applied to Bengali the browser will only select the first consonant+virama in a cluster if the virama is visible

Interactive test: When ::first-letter is applied to Tamil the browser will only select the first consonant+virama in a cluster if the virama is visible 
<a href="https://github.com/w3c/line_paragraph_tests/issues/71">https://github.com/w3c/line_paragraph_tests/issues/71</a>


For Devanagari and Bengali, Gecko only highlights the initial character+virama, whereas Blink, and Webkit select all clusters as a single unit, whether or not they are conjuncts or are rendered with a visible virama.

For Tamil, all browsers select only the first grapheme cluster (as expected).

WebKit browsers should not select the full consonant cluster if the virama is showing.</pre>
