Maybe not a bug, just and inaccessible sprite.
The sprite for automation science technology is not available via the rich text ([technology=automation-science-pack]). While this is logical as there is no technology for the automation science packs, the sprite exists as \data\base\graphics\technology\automation-science-pack.png; it's just inaccessible.
Technology icons differ from the actual science pack icons ([technology=_____-science-pack] vs [item=_____-science-pack]) and there are both sprites available for all but this one science.
[0.17.79] automation science pack technology sprite not available
Re: [0.17.79] automation science pack technology sprite not available
Thanks for the report. Because there's no technology you can't use the technology rich text icon. That's how that works and isn't a bug.
If you want to get ahold of me I'm almost always on Discord.
