Item filter can make item labels invisible even without any alpha value 0

How to reproduce:

- Any matching block with RGBA text/background color + Continue
- Any matching block with RGB text/background color

Expected result (1 of these):

- override first block color with second block color, keeping first block alpha
- override first block color with second block color, using default alpha (240 - slightly transparent)

Actual result:

- override first block color with second block color, using alpha = 0 (completely transparent)

Minimal example (uncomment 255 to fix it):

Show
SetBackgroundColor 100 255 100 255
SetTextColor 100 255 100 255
Continue

Show
SetBackgroundColor 255 100 100 # 255
SetTextColor 255 100 100 # 255

I only got this respone so far, haven't seen any patch notes mentioning this problem so I assume the answer is: no.
