Eyyyy this issue's fixed now, I think! Thank you!When Bulbapedia's wiki pages are viewed in a half-window (e.g. using windows-left or windows-right or aero snap functionality in general), the right-most part of the wiki page is uninteractible. Example:
Eevee (Pokémon) - Bulbapedia, the community-driven Pokémon encyclopedia
In the infobox on the right, right under EEVEE where it says Evolution Pokemon, the left half of the word 'evolution' functions as a hyperlink, but anywhere to the right of the letter i (anywhere on the page, not just the infobox) is uninteractible. If I expand the size of the window, more of the page on the right becomes interactible until eventually the ad frame reappears, and everything works again.
It definitely seems to be an issue with that ad frame on the right of the page interfering with clicking on stuff on the page when the webpage isn't viewed near full resolution.
OS: Windows 10 x64
Resolution: 1920 x 1080
This issue was noticed first in Chrome (version doesn't seem to matter), but the issue can be replicated in Edge and Firefox.
