@tspivey: Please update Firefox to 66.0 and try again. This issue could be a regression.

Upgrading Firefox didn't fix it.

Hi all,

I looked at this issue and know exactly what's happening, but don't have an idea on how to fix it efficiently.

Using the provided HTML snippet, I found that if you press the B key, NVDA will report the entire button content. But, the paragraph that contains it is long enough so that NVDA will split it in two lines. However, when setting up the quick navigation gesture for formField, we have readUnit=textInfos.UNIT_LINE, meaning that we will only report the first line of the TextInfo (obviously to avoid reporting a lengthy textbox content).

What we would need in the case of formField is to set this readUnit value based on the role of the queried control. Looking at the code in speech.speakTextInfo(), the way to retrieve this role seems slow, so I don't know if it's a good idea to use it inside the TextInfoQuickNavItem.report() for instance.

Any ideas?

In other words: If you increase the value in the option "Maximum Number of Characters on One Line" from "100" (default) to "120" in the Browse Mode NVDA Settings, this issue doesn't occur. Therefore I wasn't able to reproduce it because this value is always set to "120" on my systems. (I know that this is just a workaround.)

Exactly! But forget about my last message as I found a cheap way to check the role of an NVDAObject from a TextInfoQuickNavItem. Fixed by #9401.
