Date input type

I’ve got a plugin that I’ve developed for a while now. The plugin for sits in the admin screen. I’ve got a date input box using the below code. In WordPress 5.5.x and below this worked fine, but in 5.6 and above it isn’t working correctly and is shown with the picker having no width instead of its actual work. Any ideas on how to resolve this within the admin screen?

<input type='date' name='start_date' value='' data-date-inline-picker='false' data-date-open-on-focus='true' />
