Open animation doesn't work initially when title:false used

[beermad]

jquery-confirm version: v3.3.4

I'm submitting a ... (check one with "x") [ X ] bug report [ ] feature request [ ] support request

Current behavior:

When "title:false" is set, the open animation doesn't happen the first time jquery-confirm is invoked on a page. The animation happens when the dialogue is closed and if it's invoked again without reloading the page, the opening animation does happen.

Expected behavior:

Opening animation would be expected to happen on first invocation.

Steps to reproduce:

1. Configure a dialogue with "title:false".
2. Trigger a dialogue. No initial opening animation
3. Remove "title:false".
4. Reload page.
5. Trigger a dialogue. Opening animation happens.

Other information: Only a minor problem, as I'm sure I'm the only person who even notices on my site. Thanks for a very useful utility - I'm liking what I can do with it.
