Subject: Manipulation: Use textarea for missing IE defaultValue check
X-Git-Tag: 2.1.0~4
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=a20494228d51c57c454ff9f10a4ba8bbdda0e49c;p=jquery.git

Manipulation: Use textarea for missing IE defaultValue check

IE11 fixed the checkbox defaultValue issue but not textarea. Rather than
creating a new detect name I'm reusing the old one to protect anyone who
is unwisely using this externally. Re-fixing the defaultValue when it
doesn't need to be done is not a problem, so leave that code for IE11.

Fixes #14716
Closes gh-1495
