When the banner form is displayed below the banner text, the placeholder in the custom amount field tends to be cut-off. We want to prevent this from happening.
- In the banners for English Wikipedia the breakpoint that currently is at 1400px should be moved to 1300px.
- In the banners for English and German Wikipedia below 1300px width (when the form is below the blue bubble)
- the interval option of "bi-annual" ("halbjährlich") should not be displayed.
- the custom amount field should have a fixed width to prevent the placeholder from being cut-off (110px seems fine in Firefox and Chrome).
