DNG Spell Check in MS Edge

One answer

AFAIK this is entirely done by the browser, i.e. not by any aspect of ELM, so I guess it not working is a browser problem.
I tried 7.0.2SR1 and 7.0.3 iFix002 - red underlining for spellcheck works for me in Edge, Chrome and FF, during editing. The red underline is sort of dotted in Edge/Chrome and a more solid wavy red line in FF.
FF 121.0.1 (64-bit) which also works now 122.0
Chrome 120.0.6099.225 (Official Build) (64-bit) - which updated today to 121.0.6167.86 (Official Build) (64-bit)
