[cosmetic][dashboard] Expanding three dots on filter box is rendered behind, not all options visible

[zuzana-vej]

Cosmetic issue (regression) - when you click the three dots on a smaller filter box, the popup with list of options renders in the background (inside the filter box component) instead of over (previous behavior) meaning it's hard for user to select their action. This is especially visible on the filter box, (could be in small charts too in theory).

Expected results

Render over so that all options are visible

Actual results

renders behind (lilmited to filter box size)

Screenshots

How to reproduce the bug

1. Create a small (in terms of height) filter box
2. Click on the three dots
3. See issue

Environment

(please complete the following information):

This one is certainly low priority, probably introduced together with #12107 and #12105

I think I see what's happening here... in SliceHeaderControls.jsx you can see that AntD's getPopupContainer is used to render the Dropdown within the chart, where it used to be rendered in the body (the default behavior). This was done to for taking a screenshot of the viz (with the "download as image" menu item) which would hide the menu, take the screenshot, and show the menu again. This took place in https://github.com/apache/incubator-superset/pulls/11778

Most likely it's caused by visibilty: hidden in 1 of Antd's components. Overriding it to visible should do the trick. I can take a look once I'm done with tasks related to explore redesign
