[Bug] Save UI inoperable for sufficiently complex tags

[CoatMcMutton]

Problem: When using the mod-options dialogue to save a tag, the pop-up containing the list of dependencies for the tag's items can become long enough to span outside of Rimworld's vertical window bounds (using 1920x1080 borderless fullscreen). The "Confirm" and "Deny" buttons are then unreachable via mouse cursor; using the "Accept" hotkey results in the tag not being saved, presumably because "Deny" is interpreted to be the "Accept" option. No other keybinds can resolve this.

Example: Tag containing four textile + leather items, enough mods to add 6+ materials. Attached screenshot shows the part that is visible and interactive on screen.

Proposed solution: Limit the maximum height of the pop-up bounding box, ideally dependent on the game's vertical resolution.
