Yeah, double click... which is, I agree, bizarre for a 'non-desktop' link setting... I know that usually works on IE11, FF, and Edge... and my android phones, and Kindle Fire... not always, but mostly... sometimes a single click even works... depends on controller state, browser cache, etc... It's quirky
Now, I'm certainly poorly qualified, but there are various issues using SVG, especially those with 'animation' in <a...> tags... sometimes they just don't work correctly ... and there are about a million 'fixes'... and about as many reasons....
One reason, here, I suspect strongly, is the available memory in the controller... many of the scripts are NOT installed locally, but are called externally... javascript, etc... , and the 'intent' to be as cross-platform as possible.
Anyway, I stopped worrying about whether that 'link' worked several firmwares ago... Sometime TOBI may get around to updating the firmware, especially with more important functional 'glitch fixes' and operational features, such as DSP, Reboot, etc... when everything is finalized on main BT data processing.
This irritating link 'quirk' certainly has nothing to do with optimizing station and data quality
