Windows Phone 7.5 has a number of search related problems.
In-Scope:
Changing to basic search
Out-of-scope:
Trying to fix the squished icon.
Detail, for future selves:
As mentioned in T140051#2466572, when observed 15-July-2016 on en.m.wikipedia.beta.wmflabs.org the search magnifying glass is squished (n.b., on 15-July-2016).

The squishing is present both when in the search modal and before any entry to the search bar. This was observed in en.m.wikipedia.beta.wmflabs.org on 15-July-2016 (not en.m.wikipedia.org, where no search magnifying glass was showing on 15-July-2016).
Additionally, the search bar doesn't fit neatly inside the bounds of the viewport on an HTC Trophy ("7 Trophy") in portrait mode or landscape mode. It just gets cut off abruptly at a white part of the search bar on the righthand side. This has been observed on both en.m.wikipedia.beta.wmflabs.org and en.m.wikipedia.org on 15-July-2016.

Finally, and it's not clear what's going on here, but often when one taps on the search bar while reading an article, no soft keyboard is displayed. This sometimes happens on updated Android-Chrome and iOS-Safari, too, so I don't know if it's a known issue, but it's sort of tricky to figure out what one should do next in this case (perhaps users understand they should tap in the search field again to get the keyboard to slide up). This has been observed on both en.m.wikipedia.beta.wmflabs.org and en.m.wikipedia.org on 15-July-2016.
