Data importer: 2 columns recognized as single one

Data importer doesn't recognize my .tsv file with 2 columns. As you can see in screenshots below this file is properly formatted. count(\t) == count(\n), I've counted this delim chars in notepad++ in Search dialog. But on import both columns are recognized as a single one. Reason is in data in one of columns. I believe you will get same behavior with this data. What should I do and where should I post this bug report? I haven't found Data Importer repo or feedback contacts.

I was able to import this data with this workaround:

Import-Csv -Delimiter `t '.\tsv\notes.tsv' | ConvertTo-Csv > 'tsv\notes.csv'

But it'd be better if no workarounds needed. Still it seems like a bug.
