textEdit applied at wrong position

Using vim-lsp with vim-ddc and intelephense, I'm working on a PHP file with a line like this:

    $node = [$r

triggering a completion at this point suggests $root as the completion, acccepting it results in this line though:

    $node = [$$root

This seems to be caused by vim-lsp, as according to the log file the language server sent the correct textEdit starting at character 14, but vim-lsp decided to apply it at character 15 instead:
