Hello Team,

I have worked on gutenberg blocks and found that block setting typography dimensions custom size is not working as expected. I have checked its with "Paragraph", "Pullquote", "Quote" blocks.

The issue is, when we change typography dimensions type from "Use size preset" to "Set Custom Size" for padding/margin both, And change it's type from "px" to any others, then it reset to "px" again. We have to select other option twicely to change its type based on requirement.

For better understanding, I have prepared its video.
