Does anndata.raw can be automatically modified after define it?

[moonbyul-99]

Please describe your wishes and possible alternatives to achieve the desired result.

I think the anndata.raw is fixed after define, according to the API documents. However, I found it can be modified automatically by scanpy.pp.normalize_total and sc.pp.log1p.

this fig shows the raw counts of a scRNAseq data, which is stored in the 'raw_counts' layer

this fig show the scdata.raw.X which is stored before applying 'normalize_total' and 'log1p' function, it is clearly to see that the .raw is modified automically.

I think the documents should be more detailed about this situation. The attributes' name "raw" seems freeze this variable, but actually not.
