Automatic update from web-platform-tests
Replace some assert_throws('Something', stuff) calls with assert_throws_dom. (#21392)
This diff was generated by running:
find . -type f -print0 | xargs -0 perl -pi -e "BEGIN { \$/ = undef; } s/assert_throws\(([ \n]*'[A-Za-z_]*') *(, *.)/assert_throws_dom(\1\2/gs"
in bash (doesn't work in tcsh, due to the $ inside "").
This does affect indentation poorly in cases when the first arg was on the same
line as the assert_throws, there was a newline after the ',' after the first
arg, and the following args were lined up with the first arg. Fixing that,
especially when there are multiple lines after the first arg, is not trivial
with a regexp.
