The word Impasto (a painting technique) seems to be flagged

In many casses if you use the word "Impasto" (a painting technique used by many well known painters) it says "We encountered a safety issue..."

But it's not in all casses.

For example, when i used the prompt:

"a house in a field, impasto painting"

It didn't work.

But when i used the prompt:

"a house in a field, with trees, impasto painting"

It did work.
