Zooming causes text fields to truncate

[all-iver]

If I enter text like "1234.56" into a small text field so that the text fills up all of the available space, for the most part the size of the text auto-shrinks to fill the available space. However, that functionality breaks when I zoom in and out - at some zoom levels the font size is too large and the field value is truncated to something like "123...". At other zoom levels the text is not truncated. Any ideas for a fix?
