Hi @BurningTreeC apologies I merged these without properly looking at them, but I think we should move them to 5.1.19 because:
* On Chrome, the new version hides the resize handle on textarea, which can be quite useful
* It's visually quite different, and I think might benefit from more discussion
* It's inconsistent with the CodeMirror editor
Would you mind perhaps starting another PR for edit template enhancements?
* remove border: none for iframe from framed.js
... inherits the iframe border 1px solid editor-border in vanilla base
* last style tweaks for editor-preview
same border-radius as framed editor
same additional space at the right as at the left
* Update base.tid
* Update base.tid
* looks actually better with this border
It turns out that IE11 has a horrible bug whereby setting the
placeholder attribute before setting the text will trigger an input
event:

There have been long standing problems with the buttons not working in
Firefox, and now a [further
problem](https://groups.google.com/d/msg/tiddlywiki/GlsruQyPOag/BAhnI2mt
BgAJ) has come to light, and been similarly hard to resolve.
On balance, I’ve decided to remove the undo/redo buttons from the
toolbar (the ctrl/cmd-Z shortcut is still operational), thus avoiding
the problems, and saving some space in the core.
