[0.17.20][MOD]CTD when opening FNEI while helmod block is pinned

[zippy]

I'm not sure if this is a game problem or a mod problem, but it just started happening with 0.17.20 and neither mod has updated so I'll post it here. To reproduce, simply add a recipe to helmod, click the icon in the block column to open that production block, and pin the production block (hit the little pin icon at the top). If you then try to open FNEI, the game crashes. Opening FNEI without a pinned production block doesn't crash, so it seems to be related to that specific combination of windows being open.

I have a similar bug with FNEI:
If the game window is too 'widescreen' to fit the FNEI window, it crashes.
Reproduce:
- Have FNEI 0.2.3 installed
- resize the game window extremely wide (3:1 or something, edit: this also seems to happen at more normal aspect ratios, when the mod window should fit)
- open FNEI and press the 2nd tab
- crash

The bugs are related. I think the crash happens when calculating the mod window vertical layout constraints.

Edit2:
Resizing when the mod window is already open works. But, after resizing any interaction with the mod window crashes the game.

I am getting this same crash with nothing pinned in Helmod, and with a standard 16:9 monitor with 100% UI scaling.

Game version: 0.17.20
FNEI: 0.2.3
