* Fix field edit bug
This fixes the field edit bug mentioned in
https://talk.tiddlywiki.org/t/possible-field-editing-bug-in-5-2-2/2884 .
* Revert "Fix visual regression in #6511"
This reverts commit c920960942f48c07e95e56e175cf2b018fb3ec9e.
* Add new class `tc-edit-fieldeditor`
This class must be added to input and select elements that are used as
field editors. This class reduces the line height of the input element
if it is displayed within the `tc-edit-fields` part of the edit
template.
This allows the same input and select elements to be used for editing
and adding fields.
* Add the new class `tc-edit-field` to the docs
The example in `Customizing EditTemplate Field Rendering` now uses the
new CSS classes.
