// Regression test for crbug.com/1138487.

|
|
// It was possible for a non-ASCII-lowercase string to be used when inserting
|
|
// into the attribute collection if a hashtable encountered it during probing
|
|
// while looking for the ASCII-lowercase equivalent.
|
|
//
|
|
// This caused such a string to be illegally used as an attribute name, thus
|
|
// causing inconsistent behavior in future attribute lookup.
