Issues with Color & Typography Settings

[ketanniruke]

While testing the features in WordPress 6.8 RC1, I identified the following issues related to typography settings in the post editor:

1. Typography Size Display & Unit Conversion Issue

• By default, typography size options appear as S, M, L, XL, etc.

• When customizing the size, it initially displays values in rem.

• If I switch to px (pixels), the rem value should be converted accordingly, but it still displays the rem value alongside px, causing inconsistency.

These issues were observed while thoroughly testing all features.

Hello and thanks you for reporting this issue,

I'm moving this ticket to milestone 6.8 for now but I'm not sure this was introduced in 6.8.

Could you please check whether the issue can also be reproduced 6.7.2? Thank you.

The editor's unit controls rarely support value conversion on unit change, so this isn't a regression or a bug.

The main reason for avoiding conversion is that it's challenging to do correctly. Let's take a simple example: PX to REM. The standard formula is pxValue / 16 = REMValue. Here, we already had to assume that the root size is 16, which can be incorrect based on user setup.

It gets more challenging when you consider fixed to relative value conversions. How do you convert 100px into a percentage when the code doesn't know what % is referring to?

Thanks for the detailed feedback. Indeed, it doesn't look like something that can be addressed in 6.8, and it may be a wontfix.
Adding close keyword for now.
