se = "bootstrap" only requests bootstrap standard errors. Since only SEs and test statistics seem to be substantially biased by nonnormality (according to simulations I am aware of, happy to be corrected), there is no need to correct that, so the default output for point estimates is the ML (or LS) estimate). But if you use bootstrapLavaan(), you can of course report whatever central tendency you prefer. I think that function still does not provide the option of bias-correction with acceleration (I forget the reason), so if you want that you could instead use the boot package and write a custom function to extract whatever information you are interested in.
