nowhere in my post did i say anything alluding to that. it's talking about how things that have no actual action ingame, such as examining something ingame, or things that usually have an action, but don't in a certain scenario, can use up a rare window. Say you craft something inside a rare window, it's going to be rare when the craft ends due to being inside the rare window, but during the timer you examine an item, the rare window will be used by the examine and there will be no moment of inspiration, despite the fact that examine isn't even an actual action that should be able to effect it, or how trying to queue up an action before the imp, say you tried to imp with a lump when the item needs a whetstone, the rare window will end because it was used by the fail improve attempt by the lump, even if you started a whetstone imp before the window would have ended had you not tried to imp with a lump.
I'm well aware of how the window works, I've made a log parser a few years ago that compares time spent doing actions to moi's to get average moi's/hour, doing something that has 0 chance for things to mess up such as grinding mining, i get 5 minutes of mining per click with no right click menu's and on average over my 100 mining grind a MOI happens every 1h55m, i've got enough of a sample size to compare other actions to to see how much this feature/bug/whatever reduces moi's/hour. When i use my imp grinding g-series key thing, i average 1 rare window every 37 hours on average over a period long enough to grind multiple skills to 95+, due to my bind being bv1v2v3v4v5 , b being repair and v being improve, it quite literally has 1/18th the rare rate of mining due to repair consuming a large amount of rare windows, and failed imps from the wrong tools doing the same thing. I don't have any exact info on how much the right clicking effects this, as right clicks don't give log messages to compare, but comparing skills that use right click menus (such as me talking to people, mailing things out, stuff like that) to ones that don't (me mining with super long timers, barely interacting with the game), there's enough of a decrease in rare windows even without g-series keys that it's not a statistical anomaly.
