Dropdown ends up off-set in HACS - Add custom repository

[pallemannen]

Describe the bug
When adding a new custom repository in HACS, the dropdown to choose type of repository ends upp beside the main content, forcing you to side-scroll to be able to interact with it, and thus cutting off the edges of the content so it gets out of view.

To Reproduce Details
HACS -> ⋮ menu -> Custom repositories -> click the Type dropdown.

Expected behavior
It should popup where the field is, either upwards or downwards, depending on space available.

Fixed in #12 for the V1.1.4 release. The dialog surface backdrop filter was removed so fixed-position dropdowns remain aligned with their fields.
