 In [changeset:"54825" 54825]:

 #!CommitTicketReference repository="" revision="54825"
 Editor: Improve how `min`/`max` font sizes are calculated for fluid
 typography.

 - Where no fluid max values are set (e.g., single or custom font size
 values), the "size" value will act as the maximum value in a `clamp()`
 function.
 - In the absence of any fluid `min`/`max` values, the lower bound rule of
 `>16px` will be enforced. This applies to custom values from the editor or
 single-value `theme.json` styles. Font sizes below this will not be
 clamped.
 - In a preset, if a `fluid.min` value has been specified, the lower bound
 rule of `>16px` won't be enforced on this value. Presets with a fluid
 object therefore, give precedence to theme author's values.
 - In a preset, if there is NOT a `fluid.max` but there is `fluid.min`, use
 the incoming "size" value as the `max`.
 - In a preset, if there is NOT a `fluid.min` but there is a `fluid.max`,
 use `size * min_size_factor` as the `min`. The lower bound rule of `>16px`
 is enforced here, because the block editor is computing the `min` value.
 This is consistent with the way minimum sizes are calculated for single or
 custom values.
