Module talk:Template invocation

Lua error: attempt to compare string with number.

At Template:Toolbar/testcases and Template:3x/testcases test cases fail with this backtrace:

Backtrace:

    [C]: in function "sort"
    Module:Template_invocation:107: ?
    (tail call): ?
    Module:Template_test_case:140: in function "getInvocation"
    Module:Template_test_case:642: in function "?"

The issue seems to be caused by template invocation, in which a positional parameter is {{=}} and at least one named parameter is present. I've added test14_equals_sign_parameter to Module:Template test case/testcases to demonstrate the issue. —⁠andrybak (talk) 14:25, 19 May 2020 (UTC)[reply]
