While working on a project that uses a lot of SVG text and other features, we have encountered some browser specific bugs, mainly Safari/Webkit, most are very old reported bugs and all of them already reported and fixed in Chromium.
[UPDATE: A fix pushed on 14 Jan 2023] SVG textLength not working correctly (Opened 2017, Chromium fixed 2017)
Safari - Bug 171805: SVG textLength not working correctly
Chromium - Issue 719522: SVG textLength not working correctly
In this specific bug (Just to prove a point) the soultion is super simple, it's an off-by-one calculation error, so I took the time to install a local webkit environment, and ported the extremely simple Chromium solution to the Webkit issue, and it works.
All it's missing is fixing the tests.
*As a part of researching this bug I found another related bug - Webkit is taking trailing line break chars into account when calculating textLength.
