#### 🎯 Subject of the issue

Experienced behavior:
<!-- Describe issue here -->
When `nf-ple-upper_left_triangle` or `nf-ple-upper_right_triangle` are placed right next to a block glyph (eg. nvim and tmux status lines) there is a 1px difference at the top of the triangles. In fact, when we magnify the image, we can see that it's not that the the upper line is missing, there seems to be some anti-aliasing effect (see screenshot below).

Expected behavior:
<!-- Please do not forget to explain what you would have expected to see -->
Glyphs should be perfectly aligned.

Example symbols:
