[2.0.45] Parameterized blueprint always shows "unknown variable" warning

[Hares]

Steps to Reproduce

1. Make a blueprint of smth
2. Mark an item signal as a parameter
3. Mark a value signal as a parameter with formula
4. Enter formula relating to the previous parameter

OR

1. Open existing, previously-valid blueprint that uses formulas based on item/recipe
2. Hover on that formula

Expected:

• Formula is white (no warnings shown)
• Blueprint can be saved
• Blueprint can be deployed
• When deployed, formula is rendered correctly

Actual:

• Formula is red with warning like "Unkown variale 'p2_r' at position 0 near 'p2_r * 25'"
• Blueprint can be saved
• Blueprint can be deployed
• When deployed, formula is rendered correctly

:D
I searched for "unkown variable".

That's another proof why we need to migrate to a more modern forums engine which has built-in duplicate protection. And reactions instead of "same here" or "+1". And post tags.
