Hello,

If one sets the preference to "MathML with SVG or PNG fallback" and on has a formula in a <div> with display: table-cell then the last word will be displayed in a new line (even if there is enough horizontal space for displaying the last word in the previous line).

Steps to reproduce the bug

1. Go to https://test2.wikipedia.org/wiki/Main_Page
2. Make sure, you are logged in and select in your preferences "MathML with SVG or PNG fallback" for formula rendering (tab "Appearance")
3. Go to a random page: https://test2.wikipedia.org/wiki/Special:Random
4. Save the following code:

<div style="display:table-cell;">The formula: <math>\lim_{n\rightarrow\infty} q^n = 0</math>. Some sentence.</div>

Actual result: The word "sentence." will be on the next line as there is a line break before it. Screenshot:

Expected result: The whole paragraph is on one line (if the horizontal space in the browser window is wide enough).

Browser: Firefox 33.0 on Ubuntu 14.04

Notes: The bug does not appear with the settings "PNG images" and "Client-side MathJax" for math rendering.

Workaround:

The Bug disappears if one changes

.mwe-math-mathml-inline {
    display: inline !important;
}

to

.mwe-math-mathml-inline {
    display: inline-block !important;
}

Necessity of a bugfix: At the German Wikibooks I write a book called "Mathe für Nicht-Freaks". Here we use <div>-tags with display:table and display: table-cell for our boxes with icons. We do not use floated divs because of this issue. So above bug occurs in each box with an inline formula.
