Commit [1] modified the function that generates HTML ids, unfortunately this was not done correctly and should have been done in all versions since 14.0. This commit fixes that by bringing the benefits that commit [1] brings (correction so that HTML Ids don't start with a number) but without the defaults that it has. See the related discussion here [2].
