bug: on mac, ស្រៈ ើ។ ខ្មែរយូនីកូដ string ends up with overlapping characters

[mcdurdin]

String: ស្រៈ ើ។ ខ្មែរយូនីកូដ

This looks like it relates to end-of-sentence marker?

As shown in the last example here:

https://mcdurdin.github.io/pheasakhmer.com/ (see language examples)

[mcdurdin]

This string has a new line immediately after the sentence marker in examples.js:

            <li>
              ក្នុងឧទាហរណ៍នេះ ស្រៈ  េ និង  ី ត្រូវបានសរសេរផ្សេងពីគ្នា តែនៅលើឧបករណ៍ជាច្រើនបែរជាបង្ហាញចេញជាស្រៈ  ើ។
              ខ្មែរយូនីកូដត្រូវការស្រៈតែមួយប៉ុណ្ណោះក្នុងមួយព្យាង្គ។
            </li>

However this happens only with Busra and not with the system font. A missing blank glyph perhaps needed for CR/LF?

With the mac system font:

Looks like a MacOS bug to me. No action for the font?

keep open as evidence against Apple

It's difficult to verify that given this only happens with Busra -- other Khmer fonts seem to be fine. Sure documentation may be difficult, but I am happy to take this issue and #5 to Apple for discussion if that helps.
