Birthdate not autofilled in html form

Question

I'm using a register formular on my page which should be filled by autofill if the user wants to. This works alright for all fields except birthdate with the following html:

<input id="birthDate" name="birthDate" class="select" lang="de" placeholder="dd.mm.yyyy" type="date" date-format="dd.mm.yyyy" value="" autocomplete="bday">

bday should be correct according to https://html.spec.whatwg.org/multipage/form-control-infrastructure.html#attr-fe-autocomplete-bday

What am I missing?

I tried to add a new autocomplete address in Chrome, but seems like it doesn't give me the option to add a birthdate in the wizard:

I can't find any information about which fields are supported by which browser unfortunately, so perhaps todays browsers don't even support it yet?

Microsoft Edge 计划在 Edge v89 中包含此功能（计划于 2021 年 3 月发布）。由于它基于 Chromium，因此 Chromium 的所有衍生物可能都不提供对其的支持。
