I think the reason is that LaTeX actually switched to TU font encoding (from OT1) for XeTeX/LuaTeX. See ltnews Issue 26, January 2017: "The default encoding in LATEX has always been the original 128- character encoding OT1. For Unicode based TEX engines, this is not really suitable, and is especially problematic with XELATEX as in the major distributions this is built with Unicode based hyphenation patterns in the format. In practice this has not been a major problem as documents use the contributed fontspec package in order to switch to a Unicode encoded font. In this release we are adding TU as a new supported encoding in addition to the previously supported encodings such as OT1 and T1. This denotes a Unicode based font encoding. It is essentially the same as the TU encoding that has been on trial with the experimental tuenc option to fontspec for the past year. The XELATEX and LuaLATEX formats will now default to TU encoding and lmr (Latin Modern) family. In the case of LuaLATEX the contributed luaotfload Lua module will be loaded at the start of each run to enable the loading of OpenType fonts." > It seems we need to define \textquotedbl until the issue is fixed > upstream.
