Description:
Given a set of 3 filters:

#1: article_namespace == 0 & "orange" in lcase(added_lines)
#2: article_namespace == 0 & "red" in lcase(added_lines)
#3: article_namespace == 0 & "green" in lcase(added_lines)

where all 3 are set to give warning (but NOT prevented), edits that trigger combinations of these filters prevent the edit entirely. For example:

Edit session 1:

1. Add line containing "GREEN"
2. Click Save page: Warning for #3 displays
3. Click Save page again: Edit goes through (correct behavior)

Edit session 2:

1. Add line containing "GREEN and RED"
2. Click Save page: Warning for #2 displays
3. Click Save page again: Warning for #2 displays
4. Click Save page again: Warning for #2 displays

...etc. The edit is prevented entirely, stuck in a loop.

5. Click Cancel (abandon edit)

Edit session 3:

1. Add line containing "GREEN, RED, and ORANGE"
2. Click Save page: Warning messages for #1 and #3 display
3. Click Save page again: Warning message for #2 displays
4. Click Save page again: Warning messages for #1 and #3 display
5. Click Save page again: Warning message for #2 displays

...etc. The edit is prevented entirely, stuck in a loop.

6. Click Cancel (abandon edit)
