This pre-sale news may come as somewhat surprising to some (including this writer), but likely a relief to Disney. Solo had some negative attention after the original directors were fired and replaced with Ron Howard. That has pretty much dominated the topic of conversation concerning this movie, but it looks like that either general audiences aren't aware/don't care about it; they're just excited to see a new Star Wars movie. A Fandango survey reports that 85% of those who answered claim Han Solo is their favorite Star Wars character, so that could be a big contributor as well.
