This margin is not needed and doesn't exist in the mobile view.
It causes a bit of a problem in desktop topics with no categories and more prominently in PMs in the desktop view.
There's a small TODO here where the rest of the extra-info-wrapper styles should all be moved to header sylesheets.
Previously if upload had missing width and height we would calculate
on first use BUT we (me) forgot to save this to the database
This was particularly bad on home page cause category images (when old)
miss dimensions.
This allows fidelity in controlling excerpt (text that shows up when you pin a topic or link to it externally):
```
I am some text
[excerpt]
This is some **custom** markdown that should be the excerpt
[/excerpt]
More text
```
Previous solution relied on DIVs, unfortunately DIVs do not play well,
by design with mixing markdown unless you have a preceding newline eg:
```
<div class='hello'>
this will be treated properly as markdown
</div>
```
This extra newline is not desirable.
I am also considering adding
```
[div class=excerpt]
[/div]
```
This would offer lots of flexibility to themes and plugins that do not want the extra annoying newline.
As per the documentation for KEYS
```
Warning: consider KEYS as a command that should only be used in production environments with extreme care. It may ruin performance when it is executed against large databases. This command is intended for debugging and special operations, such as changing your keyspace layout.
```
Instead SCAN
```
Since these commands allow for incremental iteration, returning only a small number of elements per call, they can be used in production without the downside of commands like KEYS or SMEMBERS that may block the server for a long time (even several seconds) when called against big collections of keys or elements.
```
- Now applied to all images over 150x150px
- Stores the width and height in the WeakMap rather than using
percentages for accuracy
- When oneboxed images are hidden, they are given a subtle border for better
visibility.
- Don't apply when in the composer. Causes flickering.
With our recent move to SVG icons, the font file does not work in the wizard. I've opted for path2D, which accepts an SVG path
Path2D is not supported by IE11 but the chances of admins running the wizard on IE11 are practically none.
