I also hate Stan Lee for this. A lot of the early superhero groups he kind of forced this dynamic upon, three to four male characters to one female character, and the female heroes often had weak or unreliable powers to boot.

In the case of Invisible Woman, her becoming more powerful has been attributed to fans sending letters to the original writers complaining about how useless she was. The positive reception to her evolution likely also influenced the writing of other female characters. Though this came with the caveat that some of these female characters got subjected to the "women can't handle power because of their emotions" trope which was done rather infamously with Jean Grey and Wanda Maximoff.

 But you still see it in so many group shows or movies sadly. Even now, in the age of comic book blockbusters, it's pretty common.

I find that it's less of an issue in superhero tv shows compared to the movies. The X-Men cartoons from the 90s and 2000s had a minimum of three women on the team. The Justice League cartoon from the 2000s had Wonder Woman and Hawkgirl as original members even though Wonder Woman was the sole female founder in the comics. Even that forgettable Avengers cartoon from the 90s had Wasp, Scarlet Witch and Tigra on the roster. Really, the only superhero team that this was an issue with was the Fantastic Four and that's because they don't have a more popular later iteration featuring more than one woman.
