Bundled Themes: Minor styling issues with blocks in widget areas

[noisysocks]

Some of the WordPress bundled themes have minor styling issues when there are blocks in a widget area.

• Twenty Twenty-one: Headings in Latest Posts block are too large.

• Twenty Seventeen: Extra padding in Latest Comments block.

• Twenty Sixteen: Extraneous separator above Latest Comments block.

• Twenty Fourteen: Text has low contrast in Latest Comments block.

• Twenty Thirteen: Extra padding in Latest Comments block.

• Twenty Ten: Extra padding on left of Latest Posts block.

Fixed minor styling issues with blocks in widget area

Adding this, since I started working on it before the original patch was created. I believe my diff is a bit more comprehensive.

I don't see the TT1 issue when running the latest Gutenberg plugin, maybe some these things were fixed in Gutenberg?

Thank you @sumaiyasiddika and @danieldudzic for the patches.

I tested 53422.2.diff and it fixes most all of the issues. The only one I can't verify is the removal of the extraneous separator in Twenty Sixteen.

Here are screenshots:

• Twenty Twenty-One, latest posts size looks correct

• Twenty Seventeen, extra padding is fixed

• Twenty Sixteen, not sure if the extra separator is fixed or if padding is correct

• Twenty Fourteen, text contrast is fixed

• Twenty Ten, padding is fixed
