Encoded Text save as file type CSV (3.6.0)

Writer’s Save As option now (LO 3.6.0, Windows7) seemingly attaches a CSV extension for save as type “Text Encoded” where previous versions attached a TXT extension. Is this a bug?

At the moment there are two bug reports:

Bug 52451 - UI: FILESAVE as Text (encoded) should offer .txt as file type and name extension (v rc)

Bug 53071 - writer has no more option to save as text file (v release)

Fixed in LO 3.6.2.
