As of when? Also you do realize Merriam-Webster has added more modern terminologies with a modern viewpoint on them? Dictionaries will enter a word based on how the public uses them. (For example, "they/them" pronouns made it into Merriam webster lately and that's not even that old). So to cite dictionaries as the final authority on something is basically the same as citing the masses to prove what is true.
This definition puts a positive spin on the word "woke", but ignores the fact that wokeness has zero qualms with changing history, ignoring history that doesn't help its agenda, etc.
For example, the wokes will not call out anti-Asian racism or anti-Semitism in the black community because wokeness cannot call out blacks on anything right now. If you mention how any white person or people groups have suffered in the present or past, they don't tend to care. (For example, many Italians were mistreated when coming to America, to the point where some people who could pass for English changed their last names to avoid being prejudiced). But wokes likely either aren't "aware" of that fact, and if you enlighten them on it, they sure as heck ain't "actively attentive" to it.
You see, if "wokes" were really aware and actively attentive to racial and social justice problems, they'd advocate for equality of opportunity, and equal treatment of all races (and not just revenge). The solution to every problem is not the antithesis. Their antithesis to racism is racism. Same with sexism. Wokes are the most asleep to facts and solutions.
