Does trisyllabic laxing occur in Latin words like 'decision' before entering English?

There’s a phenomenon called Trisyllabic laxing where the vowel in a stressed syllable is shortened if two (or more) syllables follow. If the stressed vowel is in at least* the penultimate syllable (third-last syllable of the word) then it must be lax. It’s fairly common in English and mostly occurs when Latin suffixes are attached to a word.

Examples:

• Profane, profanity — [prəˈfeɪn] -> [prəˈfæn.ə.ti]
• Sincere, sincerity — [sɪnˈsɪə] -> [sɪnˈser.ə.ti]
• Impede, impediment — [ɪmˈpiːd] -> [ɪmˈped.ɪ.mənt]
• Divine, divinity — [dɪˈvʌɪn] -> [dɪˈvɪn.ə.ti]
• Michael, Michaelmas — [mʌɪkl] -> [mɪkəlməs]
• Profound, profundity — [prəˈfaʊnd] -> [prəˈfʌn.də.ti]
• Provoke, provocative — [prəˈvəʊk] -> [prəˈvɒk.ə.tɪv]

The above words have a very regular pattern of vowel change which is summarised below:

• [eɪ] -> [æ]
• [ɪə] -> [e]
• [iː] -> [e]
• [ʌɪ] -> [ɪ]
• [aʊ] -> [ʌ]
• [əʊ] -> [ɒ]

However, in some cases, trisyllabic laxing appears to take place when it should not have done so. For example, Christ [kraɪst] vs Christmas [ˈkrɪs.məs], even though the stress syllable in Christmas is followed by one syllable yet it gets laxed. In such cases, the anomaly is caused by later sound changes. Christmas was a three syllable word (stress on first syllable) when Trisyllabic laxing applied. (Full explanation here)

In some words, it seems to have applied within Latin. That’s actually what I’m asking.

Examples:

• Decide, decision — [dɪˈsʌɪd] -> [dɪˈsɪʒ(ə)n], comes from Latin decisionem
• Collide, collision — [kəˈlʌɪd] -> [kəˈlɪʒ(ə)n], comes from Latin collisionem
• Divide, division — [dɪˈvʌɪd] -> [dɪˈvɪʒ(ə)n], comes from Latin divisionem
• Reside, residue — [rɪˈzʌɪd] -> [ˈrɛzɪdjuː], from Latin residuum

Questions:

• Did trisyllabic laxing apply to these words within Latin (before entering English)?
• Is trisyllabic laxing active in Latin?
