BUG: DimensionSwitcher dropdown not visible at specific zoom levels

[c4ll-m3-j4ck]

Description

At certain browser zoom levels, the language selector dropdown disappears. This only affects the DimensionSelector component and none of the other dropdowns in the primary toolbar.

Steps to Reproduce

Set your browser zoom to something like 50% (we have seen this vary from computer to computer depending on the available screen-size).
Click to toggle the DimensionSwitcher

Expected behavior

The dimension-selection dropdown should appear

Actual behavior

The dimension-selection dropdown does not appear

Affected Versions

Neos: 8.3.5

UI: 8.3.4

I have investigated this issue some more:

It appears that the dropdown for the single-dimension-selector is appended at the wrong dom-node as it gets appended directly to the body-tag. Every other dropdown (including multi-dimension-selector) gets appended to the respective dropdown dom-node.

Starting at a certain zoom-factor (in my case it is 33% but again, this seems to vary from computer to computer), the misplaced

dom-node for the dropdown gets its style-attribute updated to simply be style="display: none;" and is therefore not shown.

Will be resolved with the release of 8.3.6.
