Summary: Web performance: texvc math images do not specify width
and height attributes
Product: MediaWiki extensions
Version: any
Platform: All
URL: http://en.wikipedia.org/wiki/White_dwarf
OS/Version: All
Status: NEW
Severity: enhancement
Priority: Normal
Component: texvc
AssignedTo: [email protected]
ReportedBy: [email protected]
The <img> tags generated by our math module do not list the width or height;
this can delay page rendering while the image is loaded, or cause the page to
reflow and jump around after the loading is complete:
<img class="tex" alt="E_k \approx \frac{N (\Delta p)^2}{2m} \approx \frac{N
\hbar^2 n^{2/3}}{2m} \approx \frac{M^{2/3} N^{5/3} \hbar^2}{2m R^2}."

/>
Note we probably need to change the math table so we actually record the
size...
