Content Cache push button disappears with result output hidden

Contrary to the R9 WIP, the Content Cache Push Content button disappears when hiding the result output. This also happens in the WIP.

This is in Version 8 SR22 (8.22.25217.12451, 2025-08-05) on Windows 11.

The Content Cache Push Button also disappears when the component is hooked up when the solver is not enabled. In that case it does not reappear when the solver is enabled again.
