From OTRS:
I have notice some problem with the way that Wikipedia app handle the text size. Although the text size option is working as intended and it increases or decreases the font size, it > doesn’t not preserve the Typography of the article. By that I mean, after increasing/decreasing the text size from the default size, the line spacing is either too little or too much, respectively. This is more significant in larger size as lines are too close and crapped up together.

Investigation of issue
It appears that currently this line spacing issue is not occurring on phones, but instead is only affecting tablets. Further more, the curious nature of this bug is that the spacing is too large for the smallest dynamic size and too small for the largest dynamic size.
Working with @Mhurd, we located a CSS style override that is causing the line spacing issues on tablets. Currently the line height is manually being set to 27px within the <p> tag in the <div class="content_block" id=content_block_0"> div on the article view. Removing this CSS override from misc.less fixes the spacing issue for tablets. Unfortunately, outright removing this override also affects phones, causing the linespacing to shrink visibly.
Proposed solution
Only apply the following override on phones, and turn it off for tablets.
.content p {
line-height:27px;
}
