According to Unicode Standard Annex #14 (Line Breaking Properties: http://unicode.org/reports/tr14/) the character 0x103D0 (in Old Persian) is a visible word divider. However in firefox this character is treated like a regular letter and firefox treats the whole text as one giant word. So far this problem has been observed in all tested systems namely: Firefox 2.0 under window$ and Firefox 1.5 under Linux amd window$.

We've integrated ICU4X line segmenter in bug 1719535, which is UAX 14 compatible.

The following testcase is grabbed from the URL.

Tested on Firefox Nightly 2023-08-07. When double-clicking on the forth character 𐎺, Firefox selects "𐎺𐏀𐎼𐎣", with each end stops at '𐏐' (U+103D0 Old Persian Word Divider).
